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

2020-4-8 Cost-efficient Transport for Open-pit Mines. 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.

Contribution to Cost Estimation in Open Pit: Aggregates

Note that capital costs are expressed in dollars and operating costs in dollars per short ton of material (ore and waste) mined. All costs are based on daily capacity of the mine (X) in short tons per day of material (ore and waste) moved.

Mining Costs CAPEX vs. OPEX UndervaluedEquity

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).
