Jul 07, 2017· The processing for limestone for these products is described below. The first process takes place at limestone mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw limestone is further processed.
The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled and screened into pieces ranging from one inch to four inches. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong.

Most of Mozambique's mining and mineral processing operations are privately owned, including the cement plants, the Mozal aluminium smelter, and the Temane gas processing plant. Artisanal miners produce gold and aquamarine, tourmaline, and other gemstones. Carbomoc E.E., which was the country's only coal producer, is state-owned.
Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
