* DETAILED DESCRIPTION OF WASTE Ferrochrome is an essential ingredient for the production of stainless steel, and is an alloy of iron and GENERATING PROCESS chromium with a chromium content of between 50 and 55 percent. Stainless steel depends on chrome

for its appearance and its resistance to corrosion.

Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. The ore- an oxide of chromium and iron - is reduced by coal and coke to form an iron­chromium alloy called ferrochrome. The heat for this reaction comes from the electric arc formed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2 800°C.

Tapping takes place intermittently. When enough smelted ferrochrome has accumulated in the hearth of the furnace, the tap hole is drilled open and a stream of molten metal and slag flows down a trough into a chill or ladle. The ferrochrome solidifies in large castings, while the slag is separated and stockpiled for further processing.

The product is crushed and screened to exact customer specifications. Alternatively, the ferrochrome is granulated into a flowing stream of water.

To improve total ferrochrome recovery while maintaining a high--quality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers

,__ __________________________ ..J..,;;and broken down to minus 15mm material. It then moves through a wet j igging plant where the chrome _

-and slag are separated by means of gravity or magnets .. The slag is then stockpiled into various size fractions for further use by external customers.
