Coal is a nonrenewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States. With our years in the coal mining sector, we can supply the quantity of 1000-2000MT every month.
Coal Coal is a fossil fuel, deep mined carbon and hydrocarbons. Fuel source for electricity generations. Also a good source of heating. Tons
coal, one of the most important primary fossil fuels, a solid carbon-rich material that is usually brown or black and most often occurs in stratified sedimentary deposits. We are Supplying Indonesia and Africa mined Coal . We can Supply Type 1 to Type 7 Gross Calorific Value ( 6,500 6,300 6,000 5,800 5,500 5,300 5100 and below)
Coal Product Description Coal is a combustible black or brownish-black sedimentary rock composed primarily of carbon, along with various other elements such as hydrogen, sulfur, oxygen, and nitrogen. It forms from the remains of ancient plant material that was subjected to heat and pressure over millions of years in a process known as coalification. Coal is widely used as a fossil fuel for energy generation and as a raw material in industrial processes. Types of Coal Coal is classified based on its carbon content and energy-producing capability: Anthracite Description: The highest grade of coal with the highest carbon content (86-97%). Characteristics: Hard, glossy, and produces the most heat. Uses: Industrial and residential heating, metallurgical processes. Bituminous Coal Description: Mid-grade coal with a carbon content of 45-86%. Characteristics: Soft and shiny; high energy content; widely used for power generation. Uses: Electricity production, cement manufacturing, and steelmaking. Sub-Bituminous Coal Description: Lower carbon content (35-45%) and higher moisture content. Characteristics: Produces less energy and fewer emissions when burned. Uses: Power generation. Lignite Description: The lowest grade of coal with the highest moisture content (up to 45%). Characteristics: Soft, brown, and produces less energy. Uses: Power generation, especially in regions where it is locally abundant. Key Specifications Calorific Value (Energy Content): Ranges from 3,000 to 8,000 kcal/kg depending on the grade. Moisture Content: Varies by type, with lignite having the highest and anthracite the lowest. Ash Content: Residual mineral matter left after combustion, typically 3-40%. Sulfur Content: Varies from low (3%), affecting environmental emissions. Applications Power Generation: Used in thermal power plants to produce electricity. Steel Production: Essential for coke production in blast furnaces. Cement Manufacturing: Used as a fuel source for kilns. Residential Heating: Especially anthracite coal for heating homes. Chemical Industry: As a feedstock for producing chemicals, synthetic fuels, and fertilizers. Advantages of Coal Widely available and affordable energy source. High energy density, especially in bituminous and anthracite grades. Established infrastructure for mining, transport, and usage. Environmental Considerations Coal combustion releases greenhouse gases and pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter. Efforts are underway to mitigate these effects through cleaner technologies like carbon capture and storage (CCS) and coal gasification. Coal remains a critical resource for energy and industrial processes globally, despite increasing attention to renewable energy sources.

Coal is world’s most abundant fossil fuel formed from the decomposition of organic materials, plants, vegetation that accumulated in swamps to great depths. With burial, the plant material was subjected to high temperatures and pressures over millions of years. This caused physical and chemical changes in the vegetation, transforming it into peat and then into coal. While being transformed from organic matter (peat) into coal, it underwent various stages like formation of lignite or ‘brown coal ‘, which is the lowest quality of coal, to sub bituminous to bituminous and then anthracite, which is the highest quality and hardest coal. High-rank coals are high in carbon and therefore heat value, but low in hydrogen and oxygen. Low-rank coals are low in carbon but high in hydrogen and oxygen content. In addition to carbon, coals contain hydrogen, oxygen, nitrogen and varying amounts of sulphur. Use of Coal Coal has many important uses worldwide. The most significant uses are in electricity generation. Not only does coal provide electricity, it is also an essential fuel for steel and cement production. Other important users of coal include paper manufacturers, chemical and pharmaceutical industries.
Coal, Coke And Anthracite COAL Coal is a hard, black coloured rock-like substance. It is made up of carbon, hydrogen, nitrogen, and varying amount of sulphur. Coal was form as decomposition took place in the absence of oxygen and much of the hydrogen content of the matter was eroded away, leaving a material rich in carbon. The material was compressed over the years by sand and dirt, leaving the form of a carbon known as coal.In others words we can say that Coal is an underground natural resource of energy and one of the most important primary fossil fuels, which is finding worldwide. Voltcon Resources expertise in sourcing thermal coal internationally for supply to Industries , Exporter , Importer and traders in Worldwide markets. Our goal is to be a key business partner for our suppliers and customers through delivering high quality shipments on-time and at the right quality & price, and demonstrating high reliability, strong business values and agility. Having established ourselves as one of India's leading private coal importers in the last few years, our aim is to grow into one of the largest coal Importing & trading companies in the World . Our short term goal is to grow our traded volume of thermal coal to 4 million tons per annum in the coming years with focus on India and worldwide. VOLTCON PRODUCT RANGE IS AS FOLLOWS Thermal coal South Africa & Indonesian Coal: Also known as steam coal, is used for power and heat generation. We supply Thermal Coal ranging from 3500 GAR to 7000 GAR. Anthracite Coal: A hard, compact variety of coal that has a sub metallic lustre. It bears the highest carbon content and least impurities among all major types of coal. Petroleum coke: The solid non-volatile carbon residue left after the refinement of petroleum. It is used as a source of energy, or as a source of carbon for industrial usage. Metallurgical Coal: Used in the process of creating coke necessary for iron and steel-making. We supply Metallurgical Coal to vast industries across geographies.
Coal is a flammable black hard rock used as a solid fossil fuel. It is primarily made up of 65-95% carbon and also contains hydrogen, sulphur, oxygen and nitrogen. It is a metamorphic rock formed from peat, by the pressure of rocks laid down later on top.
Coal is one of the important primary fossil fuels and a source of energy. It is a solid carbon-rich material, sedimentary deposit composed predominantly of carbon that is readily combustible. Its color is black or brownish-black. Coal has a composition that consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.
