How to Extract Precious Metals From Sulfides Sciencing

Extract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers. Crushing begins the separation process by preparing the ore to be floated in water. First, the ore is crushed using a gyratory crusher to reduce the ore to 6inch diameter pieces.

Froth Flotation Process 911metallurgist

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (waterrepel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

certain limitations and disadvantages when compared to flotation. Because of the increasing demand on phosphate rock for fertilizers, it is becoming more and more common to mine and process low grades of phosphate deposits. The majority of these low grade deposits are of sedimentary phosphates and the rest are of different origins.

Ore deposits formed by oxidation and supergene enrichment

An especially important class of residual deposit is formed by both the removal of valueless material in solution and the solution and redeposition of valuable ore minerals. Because solution and redeposition can produce highly enriched deposits, the process is known as a secondary enrichment.

Froth flotation Wikipedia

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

through the flotation cell, where it is saturated with gas. It is then sent to a flotation vat, where the deposits, combined with the gas, are suctioned or scraped off the surface, depending on their viscosity. The clear must is then collected continuously. Batch flotation Batch flotation is based on the same principle as continuous flotation.

Nickel: Extraction and purifiion

Apr 24, 2010 · Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction. Nickel is extracted from its ores by conventional roasting and reduction processes which yield a metal of greater than 75% purity.

flotation process – i Design

For sulfide ores, on the other hand, selective flotation normally follows the crushing and grinding stage and requires an optimal degree of liberation. In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in the orewater mixture, or
