holes are drilled in the ore and filled with explosives in the same way as in open pit mines. the mined ore is then driven to a crushing plant and crushed into smaller pieces before onward transport to the concentrator where it is crushed again to form fine sand and the metal-rich components are separated by a series of refined methods.this company wanted to apply new strategies that mitigate safety challenges in its open pit mine. teleoperation was applied to address these concerns. this article outlines the application of hard-lines teleop system for use on various projects during the mines operating schedule starting in 2015.

In open-pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. this method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward.mine production schedules will allow a milling rate of 715,000 tpy ore at an average head grade of 4.6 gt gold from the combined open pit and underground operation. the overall process is based on crushing and sag milling run of mine ore, followed by flotation to produce concentrate which is to be fed to a pressure autoclave.
blasted ore from the open pit that is directed to the mill undergoes primary, secondary, and tertiary crushing to reduce the ore size, increasing the surface area to facilitate the release of minerals. the crushed ore is fed to the concentrator where it is mixed with mining cost service continues to be a useful reference on a wide range of topics for early stage mine planning through to fill the gaps on more detailed studies. mining cost service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
