Low cost operating gold mine

For 1999 and beyond, mining cost per ton is expected to be in the range of $0.85 to $0.90. The depth of the pit and the height of the heap leach pad impact the truck-haul cycle time and unit cost, which is the most significant component of mining costs. Processing - Rates The crushing/processing rate is 21,500 tpd. It is expected to rise to ...

Cost-efficient Transport for Open-pit Mines | E & MJ

An innovative technological approach to skip haulage could optimize costs and energy efficiency in hard rock mines. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems. Mine trucks that weigh between 106 and 260 tons, and ...

Mining Costs

In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200-400 meters depth in bulk tonnage.. The mining costs are estimated in a mining company''s feasibility study which, when available, can be found on the company''s website (often hidden between the news releases).

How to profit from low-grade gold mines

 · Generally speaking, one gram per tonne works for open-pit mines, but underground gold mines require at least 2.5 g/t to be economic. Open-pit mining is either done with a fleet of haul trucks (some now automated) or an in-pit crushing and conveying system (IPCC). Underground mines are accessed via a shaft or ramp.

Open-pit mining

Typical open cut grades. Gold is generally extracted in open-pit mines at 1 to 5 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia.. Nickel, generally as laterite, is extracted via open-pit down to 0.2%. Copper can be extracted at grades as low as 0.11% to 0.2%.
