Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart. However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground
Learn MoreA gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent. and a steep increase in mining costs made further development completely unfeasible using traditional mining approaches. Application of advanced analytics should make it possible to maintain the mining equipment at
Learn MoreOther gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air
Learn Morebegin to plan for the development of the mine. This phase of the mining project has several distinct components. 1.1.2.1 Construction of access roads The construction of access roads, either to provide heavy equipment and supplies to the mine site or to ship out processed metals and ores, can have substantial environmental impacts,
Learn MoreBlock caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

Learn MoreThe experiment aimed to reduce drilling costs, lower exploration costs, maximize mine safety, increase the possibility of finding new prospects, and increase the life of mine. The equipment used
Learn MorePanning for gold was also known as "placer mining." Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.

Learn MoreMining is a major worldwide industry producing everything from coal to gold. According to a PWC annual report, the top 40 mining companies have a market capitalization of $748 billion as of April 2017.The industry as a whole saw a slump in 2015 but since then the sector has recovered due to rising commodity prices.

Learn MoreGold prospecting and identifying gold-bearing areas have become increasingly more feasible, due to research developments on the geological process of gold formation. (See References 1.) Gold bearing areas, mostly throughout the western United States, have drawn and sprouted entire communities based on prospecting.
Learn MoreThis guide to mining valuation will teach you all you need to know to value an asset! The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mining plan produced in a technical report (like a Feasibility Study). Without such a study available, one has to resort to more crude metrics.
Learn MoreIn many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.
Learn MoreWith the rising price of gold and the limited amount of mineable land, people are now focusing on the recovery of fine gold. Some rivers of the world have been sluiced as many as 6 times, yielding profitable gold each time – and demonstrating that traditional sluices can have very poor recovery. Gold Processing Equipment like the IGR500 focuses on the recovery of the Fine Gold
Learn MoreOpening a new mine or expanding an existing operation can be a challenging and daunting task. Aside from assessing and evaluating social-environmental concerns and designing the mining and material movement approach, the first question often asked is, "how much will it cost us to mine?" This may need to be determined even before you decide that
Learn MoreHydraulic mining uses water power to fracture and transport a bench of Earth or gravel for further processing. Hydraulic mining is used for placer deposits of gold, tin, and other metals. Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines).
Learn MoreWhether you go the route of gold-mining stocks, or a gold-backed ETF, the other key factor to consider is asset allocation. Such a decision is highly personal: If owning a somewhat non-correlated asset like gold helps you sleep at night and stick to your broader financial plan, then it can be a useful addition to your portfolio.
