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 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.

Nigeria Minerals, Energy and Power by Limult
Nigeria has a variety of both renewable and nonrenewable resources, some of which have not yet been effectively tapped. Solar energy, probably the most extensive of the underutilized renewable resources, is likely to remain untapped for some time.
Resources extraction
This is the most important sector of the economy. The most economically valuable minerals are crude oil, natural gas, coal, tin, and columbite (an iron-bearing mineral that accompanies tin). Petroleum, first discovered in 1956, is the most important source of government revenue and foreign exchange. Most of the oil output comes from onshore fields in the Niger delta, although an increasing proportion of the crude is produced at offshore locations. There are oil refineries at Port Harcourt, Warri, and Kaduna. Nigeria has been a member of OPEC since 1971.
There are vast reserves of natural gas, but most of the gas produced is a by-product of crude oil. In the past this was burned off, as there was no market for it, but production has since increased, and Nigeria became a globally ranked exporter of this commodity. Production has often been interrupted by protests, as the inhabitants of the oil-producing regions have demanded a larger share of the revenues.
Nigeria possesses significant reserves of coal, but these deposits are being developed gradually. Coal is used by the railroad, by traditional metal industries, and by power plants to generate electricity. Coal mining, initially concentrated around the city of Enugu and its environs, began in 1915. It declined after the late 1950s with the discovery of oil but subsequently increased. Substantial coal reserves of varying quality can be found in south-central states in a band that stretches from Benin to Cameroon. Deposits discovered more recently in the southwestern part of the country at Lafia-Obi are being developed for the Ajaokuta steel complex.
The Jos Plateau, where tin mining began in 1905, also contains columbite. By the early 21st century, the country’s tin-smelting capacity had not been reached, a result of diminished world demand in the late 1980s; production of columbite has also declined since the mid-1970s. There are iron ore deposits in the Lokoja area, and limestone occurs in many areas, where it is widely exploited for manufacturing cement and for use in the steel industry. Extensive iron ore deposits found in Kwara state have been exploited since 1984. Other mined minerals include gypsum, kaolin, barite, gold, sapphires, topazes, and aquamarines. There are also uranium deposits in the country.
