Coal Mining and Processing Industry in Nigeria by Limult
Coal remains a dominant source of electricity generation, a fuel for iron and steel production, an important entity among road construction materials and a commodity for foreign exchange earnings for many nations.
The exploitation of minerals from the earth, represents one of
man’s early areas of civilization.
No nation experiences significant advances in technology and diversification of economy with the associated increases in foreign exchange and creation of jobs for her populace without mining. It is on this premise, that researchers, investors and the government view mining and processing of local coal deposits as a great potential.
The modern Coal Mine
A modern coal mine is a highly mechanized industrial plant that has to meet strict standards of engineering design and operation. The size, power, strength, monitoring and control features, and automation of mining equipment.
The Mining Process
The coal mining process consists of several sequential stages:
(1) Exploration of a potentially economic coal seam to
assess minable reserves, environmental issues, marketable reserves, potential
markets, and permitting risks;
(2) Analysis and selection of a mining plan
(3) Securing the markets
(4) Developing the mine
(5) Extracting the coal
(6) Processing the coal if necessary
(7) Decommissioning the mine and releasing the property for
post-mining use.
The two essential requirements that must be fulfilled before
a prospective coal mine can enter the development stage are confirmation that
there are sufficient minable reserves of adequate quality with no unacceptable
environmental or permitting risks, and confirmation of an assured or contracted
market for a substantial fraction of the coal that will be mined.
Coal seams can be mined by surface or underground methods, with the choice of mining method dictated by both technical and economic factors.
The important technical factors are the thickness of the coal seam, the depth of the coal seam, the inclination of the seam, and the surface topography.
The important economic
parameters are the relative costs of mining coal by surface and underground
methods including costs associated with any site-specific land use constraints,
the cost of removing the material above the coal seam in the surface method,
and the price of coal.
The price for any particular coal is related directly to coal quality due to the higher percentage of coal mined in Nigeria. The price for steam coal is dependent primarily on its heating value and sulfur content.

The Coal Mining and Processing Factory in Nigeria by Limult
The Nigeria mining industry consists of the extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks.
Minerals are an essential source of raw materials for building and chemical industries and are also a critical part of the production of everyday electronics and consumer products.
PRODUCTION AND SUPPLY
Niger and Nigeria are the only countries in sub-Saharan Africa in which coal is presently being mined as a fuel source for powerplants and domestic use.
Coals are mined either underground or through surface methods like open-pit mining. Approximately 66% of coal and 97% of non-fuel minerals are extracted through surface mining methods. Both mining methods go through a process involving three general stages.
The first stage is extraction, which includes blasting and drilling to loosen and remove material from the mine. Second stage is materials handling. It involves transporting the ore and waste from the mine to the mill or disposal area. This stage recovers the valuable portion of the mined material and produces the final marketable product. Beneficiation operations primarily consist of crushing, grinding, and separations, while processing operations involve smelting and/or refining. Each of these stages is dependent on large amounts of energy from varying sources, including electricity and diesel fuel.
Mining Machinery is a high-technological enterprise that integrates research, design, manufacture, installation and commissioning, personal training, after-sales service etc., depending on the advanced equipment and abundant technological strength, LIMULT GROUP offer one-stop service and ensure the high rate recovery of clients' mine.

Railway Development by Limult
Development of railway transportation infrastructure in Nigeria
The efficiency of the railway in the mass movement of people and goods over long distances by land is the major advantage of this mode of transport.
Rail transport is
cheap, energy saving and environmentally friendly. The railway provides a
significant stimulus for socio-economic growth and development.
For these reasons, railway is recommended for countries with large expense of land, people and resources such as Nigeria.
The railway cut into the interior of Nigeria and for the first time, provided direct access by a modern means of transportation from the coast to other parts of the country.
The railway network was constructed in Nigeria in order to enable it to evacuate minerals and agricultural raw materials and forest resources from the Interior parts of the country and also to enable the selling of imported manufactured goods in these interior locations.
It was used for linking up the different regions of the
country and thus for promoting inter-regional trade as well as increasing
industrial and economic development.
After the initial construction of the railway network in
Nigeria, there has not been any major modification or extensions of this
backbone. The network connects the major seaports of Lagos and Port-Harcourt
with the major urban centers in the country.
The Impact of railway to Nigerian
Economy
In spite of the deficiencies of the Nigerian railway system, it contributed a lot to the general economic development of Nigeria during the colonial and early independence period by making possible the development of all parts of the country for agricultural exports, specifically cocoa in the west, groundnuts and cotton in the north and palm produce in the southeast.
It facilitated the
evacuation of minerals for export from the interior parts of the country (such
as coal from Enugu and tin from Jos).
It encouraged the development of long-distance inter-regional trade in various products within.

Chemical Industry by Limult
The chemical industry consists of the companies that produce industrial chemicals. This industry utilizes chemical processes such as chemical reactions and refining methods to convert raw materials—such as oil, natural gas, air, water, metals, and minerals—into more than 70,000 different products. These products include petrochemicals, agrochemicals, ceramics, polymers and rubber (elastomers), oleochemicals (oils, fats, and waxes), explosives, fragrances, and flavors. The chemical industry is, thus, central to the modern world economy. The chemical industry is of strategic importance to the sustainable development of national economies.
What does the chemical industry produce?
The products of the chemical industry can be divided into three categories:
- Basic chemicals
- Specialty chemicals
- Consumer chemicals
Several other categorizations are used but this one is simple and helpful in this context. Outputs range widely with basic chemicals produced in huge quantities and some specialty chemicals produced in modest kilograms quantities but with very high value.
LIMULT is a leading specialty chemicals company. The core business of LIMULT in the chemical Industry is development, manufacturing and marketing of chemical intermediates, specialty chemicals and plastics.

Aluminum Smelter Industry by Limult
Aluminum smelting is the process of extracting aluminum from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.
Although abundant in the earth's crust, pure aluminum is virtually impossible to find. Until the development of the Hall-Héroult process, the available quantities of pure aluminum amounted to samples. The Hall-Héroult process enabled the mass production of aluminum. In 1888, Hall founded the first industrial smelting operation, and global production has grown ever since.
By eliminating the risk in hazardous waste materials, transforming it into valuable products with assured market offtakes, aluminum smelter waste materials such as spent potlining, butt shot-blast fines and high-sodium anode butts, can be considered as valuable mineral resources, if treated properly. If the hazards in the materials are removed while retaining the valuable chemicals and minerals, the materials can be used for beneficial energy savings and lower greenhouse gas emissions in cement manufacture.
Limult Group realises this value proposition by:
- transforming hazardous waste materials into valuable products that are safe to handle and use in other industries
- delivering products and technical support to established markets
- providing certification for regulatory compliance and chain of custody control.
Limult provides a fully sustainable solution for SPL recovery and re-use with no residual waste material.
By maximizing the value of these materials, Limult provides the smelter with the lowest cost option for responsible management of residual materials.

Thermal power Station Construction by Limult
Intelligent thermal power plant concept
With the upgrading of productivity, the complexity and dynamics of business activities and the ability to gradually exceed the capabilities of human analysis and optimization, it is necessary to rely on intelligent technology instead of humans for process management, data analysis, decision optimization, and the core goal is to achieve intelligent production activities. The high degree of unity allows the system to work together.
Intelligent thermal Power Plants value and Goals
In this theoretical context, intelligent thermal power plants have the following three values and goals. First, intelligently realizes the potential hidden danger display of the device, enabling it to operate more efficiently and sustainably. Second, let the machine replace humans and assist the staff to carry out thermal power plant management and operation and maintenance. Third, the production and operation process of the power plant will be more transparent and synergistic, making the management process more flexible and effective. Focusing on the above objectives, the construction of intelligent power plants needs to focus on the three-dimensional dimensions of intelligent sensing, intelligent control and intelligent management.
The big data analysis generated by coal-fired power generation in
thermal power plants is used as a clue to deeply explore the value of data to
create more benefits. To this end, according to the latest definition of the
industry, it can be concluded that the intelligent thermal power plant is based
on modern digital information processing and communication technology, and
integrates technologies such as intelligent sensing, control, management and
execution to achieve synergy with the smart grid. A highly efficient, safe and
environmentally friendly thermal power plant.
