Olive mill wastewater is a challenging effluent, especially due to its toxicity related to the presence of phenolic compounds. Fenton's process was analysed on the abatement of phenolic acids typically found in this kind of effluents. To overcome the main drawback of Fenton's process, a waste from the aluminium industry commonly called red mud was used as a heterogeneous source of iron.
Based on Shandong Renping Bayer red mud as the raw material, analyzing its basic characteristics, the result is that the content of total iron in red mud is %. Gasbased hightemperature direct reduction experiments are made by using a gas mixture of CO and H2O as a reducing agent. And then the reduction effect was investigated by magnetic separation experiments, to realize that ...
A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
