Concentration. There are a number of ways to increase the concentration of the wanted minerals: in any particular case, the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.

Most of that nickel is class 2 nickel, including nickel pig iron, an iron nickel alloy, a type of low-grade ferro-nickel. A small amount of class 1 or pure nickel, on average 5% of the nickel units, is necessary for steel making, All other uses of nickel require class 1 nickel, including storage batteries and batteries that power electric vehicles.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

(XRF), and microscopic mineralogical studies. Nickel was uniformly distributed in iron (hydr)oxide minerals. The pre-concentration of nickel was attempted by magnetic separation, but was unsuccessful. The effect of the type of lixiviant, acid concentration, S/L ratio, time, and temperature were investigated in the atmospheric leaching process.

Worldwide, nickel, cobalt, and platinum-group metals are used extensively. Nickel is mostly used in alloys, for example in stainless steel, aerospace alloys and specialty steel. Cobalt is the key ingredient in rechargeable batteries. Platinum group of metals is largely used in the automobile industry.

steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.
