Mineral processing Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Introduction to Mineral Processing

Variations in particular size, mass of particle, quantity of mineral, and the character of the host rock are some of the many factors that influence reagent usage. Water quality, flotation equipment size and type, temperature, and ore body variation are just a few of the variables affecting the flotation process. Copper/Molybdenum Ore

The oxidation of copper sulfide minerals during grinding

1. Introduction. In mineral processing, grinding not only reduces the particle size and liberates minerals, but also provides differential surface properties on valuable and gangue minerals allowing effective separation of them in the subsequent separation process such as flotation which exploits the difference in surface wettability on valuable and gangue minerals.

Copper Mineral Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.

Mining McLanahan

Generally in minerals processing, minerals are recovered from their ores using several operations, including comminution, sizing, concentration and dewatering. The term "minerals processing" can be applied to a wide array of industries, such as gold, coal, nickel, aluminum, oil sands, phosphate, potash, copper, iron ore and many more.
