PROCESS OF LEAD- ZING ORE FLOTATION

摘要

This method is environment-friendly and is used in the enrichment of mineral resources. Through it, the degree of extraction of mineral components is raised upon optimum technological regime.Description : an electro-chemical activation and depression of the preliminarily prepared ore is implemented. Upon impact with permanent current (with a density between 5 and 150 mA/cm<2>), the proportion of the areas of the operating and auxiliary electrode is 20:1 to 2:1, while upon operation with a variable current - between 1:1 and 1:2. The total duration of the impact is 10 to 60 minutes. Upon depression, the electrodes are made from iron, zinc, aluminium, graphite, titanium or a combination of these, and upon activation - from copper, nickel, cadmium, antimony or a combination of these. The electrodes are in the form of lamellas, and are at a distance (between the operating and auxiliary electrode) of 8 to 40 mm, located perpendicularly to the bottom of a flotation chamber or a flotation bell.
