Chrome smelting slag is the solid residue of producing chromite alloy. This kind of slag is of high hardness and very hard to deal with. However, it will be harm to environment if piled. Forui here introduces a way to recycle the chromite alloy from the slag. The waste after recycling can be used as additive of new-type building material.

Chromite smelting slag processing line is mainly to recover the chromite alloy from the chrome smelting slag. For this processing line, not only the smelting alloy can be recovered, but also the final slag can be recycled. Here Forui shares some process about chromite smelting slag. The following is a picture about recycling of smelting slag.

During the smelting of high-carbon or charge ferrochromium, slag and metal are tapped from the furnace into a ladle and separated by decanting or skimming. The recovery of chromium from the ore varies: in a good operation 90 percent is recovered in the molten metal; of the 10 percent remaining in the slag, some is in metallic form and can be ...
