Solid mine waste management is a continuous and systematic assessment of the potential
hazards, disposal, and proper utilization of waste produced in a mining company during the
mining and mineral processing stages. In ...
Equipment selection is key activity in mining operation because it accounts to more than 60%
of total operation cost. When selection of equipment is not properly done it results into over-
trucking or under-trucking. ...
Haulage of materials in Open-pit mines contributes to approximately 40%-60% of the
total operational costs. Current stricter environmental conditions, an increase in depths
and size of open-pit mines, an increase in ...
A transformation-induced plasticity phenomenon in Fe65(CoCrMnNi)35 medium-entropy alloy was investigated. According to
the X-ray difraction patterns, the as-cast specimen contains a single-phase face-centered cubic (fcc), ...

Thermal conversion of wastes is one of theperspectivesolution to ‘municipal
solid waste’ problem. Thermal conversion process entails thermal
decomposition of material with an increase in temperature. This experimental ...

To improve the speed of an atomic force microscope (AFM), one must improve the bandwidth
of its components, and the lateral XY scanner is no exception. Sinusoidal raster scans provide a
simple way of improving lateral ...
Transportation and controlling fluid flow under high pressures in pumps, valves,
boilers and heat exchangers is a common exercise in the industries. The main
challenge, however that has confronted designers and manufacturers ...
A high-speed atomic force microscope (HS-AFM) requires a specialized set of hardware
and software and therefore improving video-rate HS-AFMs for general applications is an ongoing
process. To improve the imaging rate of ...
In the present study, a systematic investigation on the effect of Fe content on the Hall-Petch coefficient of (CoCrMnNi)100-x Fex (x =20, 40, 50, and 60) medium- and high-entropy alloys (M/HEAs) was carried out. The ...
