Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing.

The Importance of pH in Flotation

Oct 07, 2014· Chromate treatment is a chemical process where a chromium compound solution is applied to a metal surface, to form a protective chemical coating of chromate. A chemical reaction occurs between the base material and chromic-acid-bearing compound to produce a corrosion-resistant film that is physically and chemically bonded to the base metal.

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is …

Hard Rock Lithium Processing

By far the most widely used reagent collector compound is the xanthate family. Xanthate remains the main chemical used in sulphide flotation with volumes of over 100,000 t/y used – and were first marketed in the US in 1928, with dithiophosphates following in 1927 and finally thionocarbamates in the 1950s by Dow.

OVERVIEW OF PGM PROCESSING

Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>

In the case of chrome plating, They use a highly soluble form of chrome known as Hexavalent Chrome or CR+6. In order to remove this form of chrome from water it must first be reduced to trivalent chrome or CR+3. After chrome reduction, the chrome is precipitated, coagulated, flocculated and removed from the waste steam by clarification.

objective, the flotation concentrate can then be further processed by high-temperature techniques (pyrometallurgy) or chemical techniques (hydrometallurgy) to produce lithium carbonate or other desirable lithium compounds. FLOTATION Flotation is used to generate a high grade spodumene concentrate (75-85% spodumene) suitable for lithium extraction.

added at the end of the flotation process, and will precipitate as Cr(OH)3 (s). Most of the chromate will appear as solids and in the dewatering process it mainly ends up in the concentrate. If the process is performed at a high pH, typically above pH 11, dichromate mainly acts as a reducing agent and remains in solution.
