1.1 PHASES OF A MINING PROJECT

1.1 PHASES OF A MINING PROJECT

Although metallic ores contain elevated levels of metals, they generate large quantities of waste. For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is

The Ore Grade and Depth Influence on Copper Energy Inputs

The Ore Grade and Depth Influence on Copper Energy Inputs

Nov 22, 2016 The study evaluated implications of different ore grades and mine-depth on the energy inputs to extract and process copper. Based on a 191 value dataset from 28 copper mining operations, seven model equations explaining operational energy costs were statistically evaluated. Energy costs for copper mines with leaching operations were not found to be significantly affected by ore grades nor

Pre-concentration of copper ores by high voltage pulses

Aug 01, 2015 The JKMRC has recently reported a novel ore pre-concentration method using high voltage electrical pulses (Part 1 of this paper). The technique utilises metalliferous grain-induced selective breakage under a controlled pulse energy input, and size-based screening to separate the feed ore into body breakage and surface breakage components, leading to ore grade splitting

Jan 01, 2021 Due to its low concentration in ores, cobalt is usually considered to be a companion metal which is of limited economic interest. The bulk of global cobalt production emanates as a by-product of extraction of commodities such as copper (~55%), nickel (~35%), and arsenic (Azevedo et al., 2018, Smith, 2001).The only exceptions, which represent a small share of the global cobalt production, are

Jun 20, 2019 The strip ratio is calculated by dividing the thickness of the overburden by ore thickness. Eg. if the overburden is 100m thick and the ore is 50m, the strip ratio is 2:1. The lower a strip ratio, the more profitable the mine will be, since less material needs to be moved. High-grade gold contained in narrow veins that snake through the rock can only be mined by excavating shafts and hoisting the ore
