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.
Crude oil varies greatly in appearance depending on its composition. It is usually black or dark brown (although it may be yellowish, reddish, or even greenish). In the reservoir it is usually found in association with natural gas, which being lighter forms a gas cap over the petroleum, and saline water which, being heavier than most forms of crude oil, generally sinks beneath it. Crude oil may also be found in semi-solid form mixed with sand and water. It is so thick and heavy that it must be heated or diluted before it will flow.
Urea is a white dry organic compound and a crystalline substance and has minimum of 46% Nitrogen calculated in dry state. This has the melting point of 132 deg F. Urea is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under pressure of 3000 psi and temperatures of around 350 deg F. Water is removed during processing and the molten matter is either converted to prills or into granules. It is generally supplied in prills or crystals/grains. Although the colour of urea is white but the crystals are larger than prills. Urea has the highest nitrogen content of all solid nitrogenous fertilizers. Urea is produced in excess of 140,000,000 tons per year worldwide, of which more than 90% of world production is destined for use as a fertilizer. Solid urea is marketed as prills or granules. The advantage of prills is that in general they can be produced more cheaply than granules, which, because of their narrower particle size distribution have an advantage over prills if applied mechanically to the soil. Properties such as impact strength, crushing strength and free-flowing behaviour are particularly important in product handling, storage and bulk transportation. Industrial Use: As a component of fertilizer and animal feed, providing a relatively cheap source of fixed nitrogen to promote growth. As a raw material for the manufacture of plastics specifically, urea-formaldehyde resin. As a raw material for the manufacture of various glues (urea-formaldehyde or urea-melamine-formaldehyde). The latter is waterproof and is used for marine plywood. As an alternative to rock salt in the deicing of roadways and runways. It does not promote metal corrosion to the extent that salt does. As an additive ingredient in cigarettes, designed to enhance flavour. Sometimes used as a browning agent in factory-produced pretzels. As an ingredient in some hair conditioners, facial cleansers, bath oils and lotions.
HMS stands for heavy melting scrap, and 1 & 2 are the two grades within that definition. Heavy melting steel (HMS) or heavy melting scrap, is a designation for recyclable steel and wrought iron. It is broken up into two major categories: HMS 1 and HMS 2. The difference between the two is HMS 1 does not contain galvanized and blackened steel, whereas HMS 2 does. Both HMS 1 & 2 comprise obsolete scrap only. That is iron and steel recovered from items demolished or dismantled at the end of their life. Because both grades guarantee a minimum piece thickness – at least 1/4inch (6.3mm) for HMS 1, and 1/8in for HMS 2 – consignments have a high density. Both also have defined maximum dimensions (usually 60in x 24in), and should be prepared to facilitate handling and charging to a furnace. This density, sizing and preparation makes for efficient furnace operation by minimising the time to charge enough scrap for a full melt. In contrast, thin mixed scrap greatly increases charging time, cutting furnace productivity. HMS is usually traded as a blend of 1 & 2, either a premium blend (80:20) or lower grade mixes (70:30) and (60:40). Our Products Coal Trading Company HMS Trading Company

We hold immense expertise in making available Copper in many forms including LME registered and non registered cathodes, billets, rods, cakes, bars, foil, sheet, granules, plates, powder, shot, turnings, wire, insulated wire, mesh and “evaporation slugs”. Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper. The most important compounds are the oxide and the sulphate, (blue vitriol
Waste Specification: European Classification: E46 EWC Code: 19.01.02 Basel Code: B10 10 The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace.
