Mining Engineering Students on Field Trip. The copper ore is crushed and then ground to a fine powder in Ball Mills. The fine ore goes to banks of Flotation Cells in the Copper Concentrator, and the Copper Sulfide Minerals are collected on bubbles. The Concentrate is dried and
Modern, automated sorting applies optical sensors (visible spectrum, near infrared, X ray, ultraviolet), that can be coupled with electrical conductivity and magnetic susceptibility sensors, to control the mechanical separation of ore into two or more categories on an individual rock by rock basis.
1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
Dec 21, 2015Earth Movers. Earth movers are heavy mining equipment that the industry would struggle to survive without and work hand in hand with bulldozers.

Effects of Gold Mining on the Environment. Although its price fluctuates, gold regularly sells for more than $1,000 per ounce. Gold nuggets are popular among collectors but are rare; most gold is found as small particles buried in gold ore. Mining just an ounce of gold from ore can result in 20 tons of solid waste and significant mercury and cyanide contamination, according to Earthworks.
Opencast mining a method of mining rock or minerals by removing them from an open pit mine situated close to the surface above ground. Outbye going towards the pit shaft from the coal face. Outcrop a place where a coal seam is exposed at the surface. Ore rock from which we can extract valuable minerals and metals.
