Minerals beneficiation is the most important process, in terms of improving the quality parameters of the processed material. The beneficiation process, depending on the grain size of the material (feed), is carried out in specialized machines and devices, including dense liquid separators (e.g., DISA), pulsating water jigs, and flotation machines.

the other hand has also caused serious problems relating to environmental pollution. Therefore, wastes seem to be a by-product of growth. The country like India can ill - afford to lose them as sheer waste. On the other hand, with increasing demand for raw materials for industrial production, the non-renewable resources are dwindling day-by-day.

The authors describe their design for a paddle-like cantilever beam sample to relieve non-uniform stress distribution in beam-bending tests of the mechanical properties of thin film applications to MEMS. We added the sample to a custom-designed system equipped with an electrostatic panel and optical interferometer. The system overcomes problems associated with using nano-indentation for ...
