also use diesel fuel for surface hauling of ore to the mill. Approximately 155 pounds of explosives are used for every short ton of copper produced in underground mines.s The average grade of the ore mined, the ratio of overlying dirt and rock (overburden) to the ore body (stripping ratio), and the depth of the pit 5Gaines, supra note 3.

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.

Improvement to milling process reduces consumption of power and inputs in Pará.

Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy.

Carmen Copper's operation current power demand averaged at 43MW for the 1st quarter of 2018. This power requirement is projected to increase to 46MW in 2018 and 2019 once the milling plant's throughputs will stabilize to 48 kTPD. In 2020 onwards, the power consumption is expected to rise to about 49MW when the mine production is at 50 kTPD.

The greatest energy input in copper and gold production is required for the comminution and grinding processes. The energy audit of mainly Australian copper and gold mines shows that 36 % of the overall energy consumption is attributable to comminution [1]. Previous studies had shown values between 18 % and 50 %.
