Characterization and Flotation of Sulfur from Chalcopyrite
sulfur ore was selected, a typical method was grinding the sulfur ore to about 28 mesh followed by froth flotation Flotation concentrates were melted and filtered to produce sulfur products with a grade of 995% These plants basically operated before 1960s [2] Hydrometallurgical processes are playing an increasingly important role in primary production of copper Copper produced by leaching 1/9/2002 As a coarse particle flotation technique for sulphide bearing ores, it was found that xanthate preconditioning of the ore results in concentrating the sulphur bearing particles to the concentrate By increasing the xanthate addition, the relative mass recovery as well as sulphur recovery to the concentrate increases This increase in mass and sulphur recovery, however, is not linear These The dynamic behaviour of coarse particles in flotation Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario Froth flotation is a process for separating minerals from gangue by taking advantage of differences in Froth flotation Wikipedia

The additional sulfur from the pyrite in the lead concentrate reduced the lead smelter's lead production because the ability to eliminate sulfur from the concentrate was lead smelter's capacity bottleneck As part of the effort to try to fix the problems, MIM installed some column flotation cells in the zinc concentrate and bulk concentrate sections of the plant In those days, the air was 8/7/2017 The company carried out a test campaign with its own Hybrid Flotation cell in the laboratory An iron ore concentrate containing 67 % Fe and 13 % S was used as the feed material The target of the test campaign was to reduce the sulfur content to below 04 % in the final concentrate The required iron recovery was at least 95 %Pneumatic flotation Application of Hybrid Flotation in the Problem: A copper ore initially contains 209% Cu After carrying out a froth flotation separation, the products are as shown in Table 1 Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process Product % Weight % Cu 1 Froth Flotation – Fundamental Principles
