Method for preparing active slag powder by utilizing chromium slag and chromium sludge
A method for preparing active slag powder by utilizing chromium slag and chromium sludge employs chromium slag, chromium sludge, waste, gypsum, waste stone powder and a carbon-base substance as raw materials, performing material preparation, mixing and homogenization, shaping, and reduction roasting and quenching, adding an alcohol amine type auxiliary agent and gypsum ingredient, or adding an alcohol amine type auxiliary agent, modified bentonite and gypsum ingredient, and together grinding to form the active slag powder with the fineness of 80 mu m and the screening tailings content of 18% or less. The method is simple in technology, small in investment, large in resource utilization amount, and free of secondary pollution or potential pollution trouble, also is capable of simultaneously recycling, decomposing and receiving chromium slag, chromium-polluted soil and other wastes, is thorough in detoxifying processing and relatively low in utilization cost, and realizes ultimate resource processing utilization.
