Limult Lead Mining and Processing Factory in Nigeria
Lead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays. Lead resists corrosion by water, so it has long been used in the plumbing industry. It is also added to paints, and it makes a long-lasting roofing material.
Lead is a health hazard to humans if it is inhaled or ingested, interfering with the production of red blood cells. Its use must be carefully controlled, and several formerly common uses of lead are now restricted by the government.
Lead paint is found in many older buildings, but it is now mostly used on outdoor steel structures such as bridges, to improve their weatherability. A lead compound called tetraethyl lead was added to gasoline as early as 1921 because it prevented the "knocking" problem of high-compression automobile engines. However, most gasoline now contains no lead, because lead from car exhaust was a major source of air pollution.
Lead is also commonly used in glass and enamel. In television picture tubes and computer video display terminals, lead helps block radiation, and the inner, though not the outer, portion of the common light bulb is made of leaded glass. Lead also increases the strength and brilliance of crystal glassware. Lead is used to make bearings and solder, and it is important in rubber production and oil refining.
Raw Materials
Lead is extracted from ores dug from under-ground mines. More than 60 minerals contain some form of lead, but only three are usually mined for lead production. The most common is called galena. The pure form of galena contains only lead and sulfur, but it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic.
Two other minerals commercially mined for lead are cerussite and anglesite. Over 95% of all lead mined is derived from one of these three minerals. However, most deposits of these ores are not found alone but mixed with other minerals such as pyrite, marcasite, and zinc blende. Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries.

Limult Kaolin Mining and Processing Factory in Nigeria
Kaolin is mined and processed for diverse end-use markets. Its versatility derives from its naturally occurring range of crystal shapes, sizes ,and layer structures. These attributes, along with desirable rheological, chemical, and optical properties, give kaolinites value as an industrial raw material.
Kaolin has limited utility in its raw form, and the majority of end-use applications require a refined product derived from a combination of controlled mining and selective processing to engineer specific properties. Kaolin mining began in the Neolithic when early humans discovered that the material could be used as a white pigment for painting and decoration.
These miners devised simple process to transform the raw mineral into a form that could be more readily applied to surfaces. The process started with digging kaolin from river banks, drying it, grinding it into a fine powder, and finally mixing it with various binders, including animal fat, saliva, water, and blood.
For thousands of years after the first kaolin-based paint was placed in the hands of prehistoric artists, kaolin mining and processing barely changed. Small advances were made as new applications were discovered, but the basic process remained more or less the same. In some parts of the world, the same small-scale mining methods that provided clay for cave art are still employed today to extract clay for mud huts, earthenware pottery, and handmade tile.

Limult Gypsum Mining and Processing Factory in Nigeria
Nigeria is known to have records of occurrences tin, columbite, tantalite, lead and zinc. In fact, mining in Nigeria he said to have started with mining of tin ore in 1905.
such mineral with great industry use and but largely underdeveloped in Nigeria, is gypsum. About one billion tones of gypsum deposits are spread over many sites in Nigeria. It is an important input for the production of cement. It is also used for the production of Plaster of Paris (P0P) and classroom chalk, etc.
Being a key input in cement production, a strategy for large scale mining gypsum is urgently required to sustain existing cement plants and meet future expansion.
The proccess of mining
The process starts by extracting gypsum rock deposits from the ground using a ‘JOY mine cutter’ that scores away at the face of the gypsum rock. This is then broken up and transported to the surface.
The rock is then crushed into smaller pieces and sent to the homogenizer, which allows for any variances in the gypsum size to be reduced, ensuring consistency in each bag of plaster. The rock from the homogenizer is ground down even further before it goes through what’s called the calcination process. Here, any water from the rock is removed in a low temperature kettle to create the first resemblance of plaster powder. This then travels through the mill, where the particle size of the powder is modified to suit the type of plaster being made.
At this stage, the plaster is almost ready! With the inclusion of a few additives that give each mix of plaster its own special properties, the plaster is pumped into bags and then palletised. Quality control checks are carried out across every batch to ensure that customers receive the same product, every time.
From here, the plaster leaves the Gypsum plant and is sent to merchants and distributors, ready for plasterers to buy. Once the plasterer mixes the product with water, it will return back into its original state, creating a plaster finish for their project.

Limult Glass Sand Mining and Processing Factory in Nigeria
Exploitation of the Non-metallic Minerals has not attained the desired level, mainly because of the various problems associated with their exploitation, development and processing for utilization. Many of the non-metallic minerals, which are vital to the industrial take off of the country, have been found in commercial quantities within the country.
They include limestone, dolomite, marble, kaolin, barite, diatomite, feldspar, quartz and silica sands, gypsum, talc, silimanite, kyanite, phosphate, salt and bentonite.
Nigeria has extensive deposits of good quartz silica sands. Many of which are associated with the coastal plain of sedimentary areas in the southern part of the country, although deposits also occur in some inland areas.
The major silica sand deposits in the country are located at Ughella–Delta State, Igbokoda, Ondo State, Baure, Katsina State, Badagry, Lagos State, and along the sandy shore line of the Atlantic, some inland deposit are also reported at Shebu, Plateau State and Ilaro, Ogun State.
Silica Sand/Quartz constitutes one of the most readily available geological materials used in industries and factories such as glass manufacturing companies. Silica Sand/Quartz are said to consist of high optimal percentage of silicon dioxide (SiO2) which is a very good chemically stable element and it remains almost the same no matter the series of cycles it may have gone through, either in transportation or re-deposition.
Quartz is silica occurring alone in pure state. Silica/glass sand on the other hand are products of weathering, erosion and transportation by rivers or/and the sea. Naturally occurring silica sands may contain some undesirable impurities like accessory haematite, rutile and dolomite etc.
Glass Sand is used in the production of various glass products: which include sheet glasses for windows, bottles, mirrors, optical instruments, chemical apparatus, electrical insulation and condensers, pipe, doors, crucibles, automobile and aircraft bodies, filters and building blocks. They are also used for making abrassives and for gravel packing in the petroleum industries.

Limult Feldspar Mining and Processing Factory in Nigeria
Feldspar is a kind of silicate minerals which contains calcium, sodium and potassium, there are many categories of Feldspar including albite, anorthite, etc. Feldspar mining process mainly applying flotation process, and Feldspar mining machines mainly including jaw crusher, ball mill, spiral chute, and concentrating table, etc.
Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including high-end ceramics and electronic-grade glass fibers. The glass and ceramic industries, in particular, are major consumers of feldspar, accounting for 95% of total consumption.
In recent times, the increasing rate of depletion of high-grade feldspar ores has resulted in lower-grade ores becoming the primary source of feldspar. This has placed added pressure on producers to further optimize existing feldspar processing methods like flotation to more efficiently produce higher grades of feldspar for the specialty glass, ceramics and electronics markets.
Process Description
Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is used for most feldspar ore beneficiation.
An amine collector that floats off and removes mica is used in the first flotation step. Also, sulfuricacid, pine oil, and fuel oil are added. After the feed is dewatered in a classifier or cyclone to remove reagents,sulfuric acid is added to lower the pH. Petroleum sulfonate (mahogany soap) is used to remove iron-bearingminerals.
To finish the flotation process, the discharge from the second flotation step is dewatered again, and a cationic amine is used for collection as the feldspar is floated away from quartz in an environment of hydrofluoric acid (pH of 2.5 to 3.0).
If feldspathic sand is the raw material, no size reduction may be required. Also, if little or no mica is present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking.

Limult Diatomite Mining and Processing Factory in Nigeria
Diatomite is the naturally occurring fossilized remains of diatoms. Diatomite is a sedimentary deposit which entirely consists of silica. Countries such as China, U.S., Denmark, Japan, Mexico and CIS were the major producers of diatomite in past few years.
The properties such as high surface area, low density, abrasiveness, high porosity, inertness, insulating properties, high silica content, absorptive capacity and brightness makes diatomite a valuable material in the market. The mining and extraction process of diatomite is complicated.
Diatomite mining and processing requires heavy earthmoving equipments and huge processing facilities. To get the desired grade of diatomite is highly energy intensive process. Diatomite can absorb liquid three times the weight of its own.
World diatomite (also called diatomaceous earth) output decreased during recession years, but now the market shows stable growth. Today the USA is world’s largest diatomaceous earth producer, accounting for about 36% of global total. Other major producers include China, Japan, Denmark, Mexico and Peru.
Main diatomite end use sectors include filter aids and fillers – together they account for 85% of total product demand. Other applications include production of absorbents and specialized pharmaceutical / biomedical uses.
