Oil sands mining operations are some of the largest mines in the world Although open-pit oil sands mines have a lot in common with traditional hard-rock mines (such as gold or copper) oil sands operators have some unique challenges due to the softness of the deposit Learn more about surface mining techniques used in the oil sands
Open-pit mining causes changes to vegetation soil and bedrock which ultimately contributes to changes in surface hydrology groundwater levels and flow paths Additionally open-pit produces harmful pollutants depending on the type of mineral being mined and the type of mining process being used
Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada Other 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
costs for modern mechanized and open cast mines to 50%–60% for the mature deep-level underground mines Worker demands for increased salaries and wages have continued to plague the industry and it is estimated that South Africa's mining industry lost more than US$1 4b in the 2012–13 financial year While workers

Before mining can commence the land needs to be cleared of timber and vegetation Alongside this process may be the collection of seeds and/or saplings for inclusion in a seedbank which will form the basis of post-mining revegetation of the site Next the top soil is removed and is usually also stored for replacement during rehabilitation
For example using surface mining techniques many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers Newly-developed machines used for grinding and crushing can extract minerals from the earth with less energy than ever before
major mining regions For the latter we have drawn upon 20 years of operating performance data from 136 mines and 4 760 individual machines – in all this represents more than 47 million operating hours Key findings • The global mining industry's open cut equipment productivity (ie annual output /
