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 Gold Mining and Processing Factory in Nigeria
The process of Gold mining begins when geologists take ore samples to determine the best places for companies to mine. The mining process can begin once the mining engineers know where gold is located and what other materials surround it. The gold is mined with open-pit mining techniques if the gold is located close to the surface.
Gold that’s located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces, and then the sand grain-sized pieces are mixed with a cyanide solution to create a watery, mud-like mixture.
However, gold is readily dissolved in a number of solvents, including oxidizing solutions of hydrochloric acid and dilute solutions of sodium cyanide. Gold readily dissolves in these solvents because of the formation of complex ions that are very stable.
Gold melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimeter) has made it amenable to recovery by placer mining and gravity concentration techniques. With a face-centered cubic crystal structure, it is characterized by a softness or malleability that lends itself to being shaped into intricate structures without sophisticated metalworking equipment. This in turn has led to its application, from earliest times, to the fabrication of jewelry and decorative items.
With more years of experience in the processing of gold ore, we have accumulated a wealth of professional knowledge and we have done many successful projects. For these years, we're dedicated in providing professional gold extraction solution for different type of gold mine.

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 poses the best capabilities, best commodities and best assets, to create long-term value and high returns. We are among the top producers of major commodities, including iron ore, metallurgical coal and copper with substantial interests in oil, gas and energy coal.

Liquefied Natural Gas Plant by Limult
The earth has enormous quantities of
natural gas, but much of it is in areas far from where the gas is needed. To
move this cleaner-burning fuel across oceans, natural gas must be converted
into liquefied natural gas (LNG), a process called liquefaction.
What is LNG –
liquefied natural gas?
LNG
is natural gas that has been cooled to –260° F (–162° C), changing it from a
gas into a liquid that is 1/600th of its original volume. This reduction in volume enables the gas to be transported
economically over long distances.
Liquefaction plants
LNG liquefaction plants are generally
classified as baseload or peak shaving, depending on their purpose and size.
The process for the liquefaction of natural gas is essentially the same as that
used in modern domestic refrigerators, but on a massive scale. A refrigerant
gas is compressed, cooled, condensed, and let down in pressure through a valve
that reduces its temperature by the Joule-Thomson effect. The refrigerant gas
is then used to cool the feed gas. The temperature of the feed gas is
eventually reduced to −161°C, the temperature at which methane, the main constituent
of natural gas, liquefies. At this temperature, all the other hydrocarbons in
the natural gas will also be in liquid form. In the LNG process, constituents
of the natural gas (propane, ethane, and methane) are typically used as
refrigerants either individually or as a mixture. Feed pretreatment and
refrigerant component recovery are normally included in the LNG liquefaction
facility. LPG and condensate may be recovered as byproducts.
How do we use
LNG?
LNG is returned to a
gaseous state at LNG import and regasification terminals around the world. Once
it has been warmed to become natural gas, it is dispersed through pipelines for
use by homes and businesses. It can be used in a variety of ways: Residential
uses for natural gas include cooking, heating homes and generating electricity,
while commercial uses for natural gas include heating, generating electricity,
manufacturing products like fertilizers, paints and medicines, and occasionally
fueling commercial vehicles.

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.
