Prof T C Rao with Prof A J Lynch Prof. T.C. Rao with Dr. B.A. Wills Editor in Chief of Minerals Engineering during XXVI International Mineral Processing Congress held in New Delhi, India, in 2012. Tadimety Chakrapani Rao (18 September 1940 – 5 September 2023), also known as T.C. Rao, is an Indian mineral processing scientist and researcher.
Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling .
A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. [1] It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. [ 2 ]
Water flow rate, table tilt angle and intensity of the shaking motion must be properly adjusted for effective mineral recovery. [6] [10] The riffles cause mineral particles to stratify in the protected inter-riffle regions. [12] The finest and heaviest particles are forced to the bottom and the coarsest and lightest particles remain at the top.
Froth flotation to separate plastics, Argonne National Laboratory Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity.
Mineral processing consists of first liberation, to free the ore from the gangue, and concentration to separate the desired mineral(s) from it. [5] Once processed, the gangue is known as tailings , which are useless but potentially harmful materials produced in great quantity, especially from lower grade deposits.

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the ...
