How to Recover Copper from Slag by Flotation

Flotation of Copper From Slow-Cooled Converter Slags. The results of flotation tests on slags cooled in air and in the induction furnace are shown in table 2-3. Examination of the data indicates that a relatively fine grind is required to liberate the entrained metallic particles. A 30-minute grind resulted in 98 percent of the pulp passing …

Flotation of Base Metals from Grinding Mill Discharges

"Conventional base metal milling practice normally consists of crushing, grinding and cyclone classification followed by flotation. It is the authors' belief that the commencement of flotation after cyclone classification leads to inferior metallurgical results and that implementation of flotation of grinding mill discharges can result in increased recovery …

A comparative study on the effects of dry and wet grinding …

This manuscript compiles various effects of dry grinding on flotation and compares them with wet grinding. Dry grinding consumes higher energy and produces …

Evaluate the Depression of High-Concentration Pyrite in …

Grinding and flotation tests were performed on a tri-mineral system containing chalcopyrite, pyrite and quartz with Cu feed content remaining the same while changing the ratio of pyrite to quartz. And 30 wt% Cr steel was chosen to represent the 'maximum ability' of HiCr steel grinding media in pyrite depression. Ethylene diamine …

Effect of reducing grinding conditions on the flotation behaviour of

Iron or 30% chrome containing balls were used in grinding. In this study, a number of grinding and flotation tests were done with natural ore samples into which 1 g of synthetic sperrylite was added. This study presents some aspects of the effect of a reducing grinding environment on the flotation response of low-S content PGE …
