Introduction to Mineral Processing cpchem

In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and non sulfide minerals as well as native metals are recovered by froth flotation.

gcse 1. Introduction to the Extraction of Metals method

The simplest definition of an ore is a mixture of a metal containing mineral and other materials ('minerals') from the surrounding rocks, which can be described as impurities with respect to what you want from the ore. Metal ores are obtained by mining and that this may involve digging up and processing large amounts of rock.

Extracting Gold  HowStuffWorks

Extracting Gold HowStuffWorks

Removing the gold bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to

The Geology of Rare Earth Elements

Rare earth elements bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined. The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig. 2).

Using Borax Flux to Refine Gold MGS Precious Metals Blog

Aug 07, 2013018332With some borax, heat, and a little know how, its possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
