Flotation of copper ores at the stage of ore preparation of fine vibrating screening
The causes of loss of metals at the concentrators and a way to reduce them were found out. A full factorial experiment on a fine vibrating screening was planned and implemented. Linear equations of the process of fine screening were obtained. Separation characteristics of screens and fine screening hydro cyclone were considered. The analysis of the products of screening and hydro cyclone with the definition of distribution of metals and minerals, the extent of disclosure for mineral by products classification was carried out. The main indicators of flotation enrichment of products of hydro cyclone and fine vibratory screening were defined, showing the advantage of the latter. The possibility of increasing the efficiency of flotation of copper ore using fine screening at the stage of ore preparation was shown.
