In order to solve some issues of Cu-Fe sulfide flotation separation at high basicity, the experiment on flotation separation of Cu-Fe sulfide at low basicity for a Cu-Ag multi-metal ores in Jiangxi province used the DT series depressor of Jiangxi University of Science and Technology. The results showed that flotation separation of Cu-Fe sulfide with the depressor DT-2# at low basicity of pH=8, the...
Based on the fact that the primary copper sulfide bioleaching has long leaching time and low leaching rate and has not been used in industry, through selective breeding, domesticated species leaching good using the scanning electron microscopy. The chalcopyrite bioleaching by A. ferrooxidans was studied. Understanding of passivation phenomenon of chalcopyrite surface and the types of passivation layer...
The mineral processing wastewater of sulfide ore is easily cause environment pollution, because it contains xanthate. This thesis applied the combined technology of ultrasound and Fenton reagent to deal with the artificial and actual mineral processing wastewater, in terms of the effects of pH value, H2O2 and Fe2+ concentration on the removal efficiency of xanthate. The results showed that combined...
According to the floatation processing characteristic with time-variation, uncertainty and complicated nonlinear relations, a prediction method of concentrate grade and prediction model of ore dressing date is proposed. This article establish a prediction model of ore dressing date based on Jordan neural network including input of influence factors and dynamic time sequence feedback of concentrate...
