chapter 7 energy use in the copper industry

% energy use underground mines use electricity for gener-ating compressed air pumping lighting ‘venti-lation and hauling miners and materials. they 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

from ore to finished product

copper is a major metal and an essential element used by man. it is found in ore deposits around the world. it is also the oldest metal known to man and was first discovered and used about 10000 years ago.

current energy requirements in the copper producing

in mining copper ore the greatest energy consumers are ore hauling and blasting. another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. the mining and mineral concentrating energies are directly proportional to the “recovery efficiency” with a typical mining operation requiring about 20 million btu/ton of cathode copper produced.

nickel mining and processing: everything you need to know

although nickel is documented being used as far back as 3500 bc by syrians who used a small amount and in 235 bc by the chinese who minted coins from nickel nickel mining itself is relatively new compared to other mined materials. dating back to 17th century germany nickel was discovered in a red-colored ore that german miners believed was copper.

how copper is made

in addition to the ores themselves several other chemicals are often used to process and refine copper. these include sulfuric acid oxygen iron silica and various organic compounds depending on the process used. the manufacturing process the process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product.

how copper is made

the current trends in copper processing are towards methods and equipment that use less energy and produce less air pollution and solid waste. in the united states this is a difficult assignment because of the stringent environmental controls and the very low-concentration copper ores that are available.
