What is beneficiation?

1. What is beneficiation or mineral processing?

Beneficiation simply means by various kinds of equipments to extract useful minerals from the tailings, in this way useful minerals will be collected for smelting. Generally there are three methods, one is by magnetic separator for magnetic materials like magnetite, one is by gravity method, most for the materials that have specific gravity differences, like Chromite, Hematite, the third one is by flotaiton, like copper ores and gold ores

2. What’s the purpose of beneficiation?

The purpose of beneficiation is get rid of useless materials and tailings from the resources, so can get one or several kind of useful materials for better use. It greatly reduce the transportation cost and smelting cost.

Introduction of Magnetic Separation

Dry low-intensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, the process being known as cobbing, and often being carried out in drum separators. Below the 0.5 cm size range, dry separation tends to be replaced by wet methods, which produce much less dust loss and usually a cleaner product. Low-intensity wet separation is now widely used for purifying the magnetic medium in the dense medium separation process, as well as for the concentration of ferromagnetic sands.
