Flotation of Pyrite Metallurgist & Mineral Processing

2019-5-6 · Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

The flowsheet principles used in the experiment is shown in Figure 1. use con.as Concentrate, The following are the same as feed

Factorial design of selective flotation of chalcopyrite

In view of the high activity of pyrite and the intergrowth of chalcopyrite and pyrite with gangue, it is required to grind ore up to 75–80% content of size–74 μm, while pH of the pulp is to be maintained at the level of 11 in all flotation circuits.

Froth flotation Wikipedia

2019-5-7 · Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
