  • The state of outsourcing in the Canadian mining industry

    Dec 01, 2018 · A complete contract can be written for a process whose outcome is welldefined and thus there is little or no need for internal control. In mining, an example would be a maintenance contract for a fleet of equipment where the desired outcome is machine availability. Thus maintenance would be (and often is) a candidate for outsourcing.

  • What are the different types of mining and how do they differ?

    As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesnt require tunnelling into the earth and is a simple method of mining that yields high production rates. The Fimiston Open Pit and the Newmont Boddington Gold Mine are two of the largest openpit mines in the world, measuring over 3.5km long, 1.5km wide and 570m deep. Both pits are located in Western Australia (WA) and produce 28 tonnes of gold per year.

    Utilising the mammoth strength of BucketWheel Excavators, moving up to 12,000 cubic meters of earth per hour, Surface mining is the process of seam mining coal and ore from the land. In this process, any unwanted earth or soil is stripped from the land and any ore or mineral that is sought after is found relatively close to the surface of the site. Because of the land decimation that occurs in Surface mining, this form of mining is controversial. Surface mining often leaves behind large areas of infertile land and waste rock as 70% of the mined earth is waste materials.

    Underground or Subsurface mining involves the digging of a network of shafts and tunnels into the earth to reach and extract the deposit of ore or mineral beneath the earth. In comparison to other methods, underground mines impact less on the environment and are much more harmful to those working within them. In the past, underground miners utilised shovels, axes and carts to retrieve valuable materials at great cost to their health. Canaries were often utilised as an early indication system of toxic gases in the mines as they would quickly perish of oxygen levels were harmful. In modern practice, underground mines are preassessed for oxygen toxicity levels and a system of ventilation machines and protocols are in place to ensure workplace safety. Moreover, relative to other forms of mining, underground mines excrete much less waste rock when accessing the ore. That being said, though, the process is a lot more expensive and difficult than other forms. Geologists and Mining Engine

    A rarely used process of mining material, InSitu or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating InSitu Uranium Mine. This solution (lixiviant liquid) works by changing the pH and Oxidation levels of the ore, leading to the ore breaking down and becoming easily extracted. For example, Sulfuric acid is generally used when InSitu Mining for copper. Looking for Mining Equipment? Visit here for more information
