The mine primarily produces platinum palladium rhodium and gold It has an estimated life of 18 years Mining Typical drill and blast narrow tabular reef mining techniques are used at Zondereinde underground mining A conventional breast mining layout is implemented the ore is transported to three ore passes handled via a dip gully
Ore is extracted from rock by heap leaching flotation or smelting Extracting ore from rock can take a lot of energy How are mined materials transported Miners use mining trucks loaders and haulage carriers to not only transport the run of mine ROM ore to the processing area but also remove overburden and waste rocks from the mine site
In 2004 annual gold production from Artisanal Gold Mining AGM was estimated at 20 30% 500 800 tonnes of total global production Swain et al 2007 A more recent study Seccatore 2012 placed production from AGM at about 392 tonnes/a or % of total output 2828 from organized mines WGC 2013 392 tonnes from AGM = 3220 tonnes

Goldstrike mine in northeastern Nevada is one of the largest gold mines in the world In 2016 the mine produced million ounces of gold Only two other operations—the Grasberg mine in Indonesia and the Muruntau mine in Uzbekistan—produced On September 25 2016 the Advanced Spaceborne Thermal Emission and Reflection Radiometer
A new open pit gold mine in northeastern Ontario has turned to automation — including nearly 300 tonne hauling trucks that drive themselves — in a bid to increase productivity and worker safety
Scrapers remove dirt from the upper layer of the placer deposits while excavators dig out the ores The ore is then collected and transported to nearby processing units Monazite contains an average of 2% yttrium and is mined in South Africa and Australia Gold Mining Gold is a chemical component with the symbol Au that springs up from
Mine to Mill which links aspects of mining and mineral processing in order to optimise the combined mining and processing stages has been under development and use for the last 20 years Implemented effectively numerous operations have experienced productivity gains from Mine to Mill in the range of 10 20%
The selected vein is 1 cm wide and parallel to the main mineralized vein population which strikes 070 and dips 70° to the SE The vein is mainly composed of visible gold grains interstitial to quartz crystals Fig 2a Thin section petrography by backscatter imaging reveals that the gold crystals commonly exhibit inclusions less than 3 μm in diameter
The mining is being implemented in three stages with the first stage involving the extraction of up to 300 000t of ore The second stage will involve the mining of additional of ore while the remaining resources within the JWD deposit will be mined in the third stage The project aims to mine 3Mt of iron ore over the three stages
The gold supply chain is a complex network of individuals organizations and processes that work together to extract refine and distribute gold around the world The supply chain begins with gold mining companies that extract the precious metal from the earth From there the gold is transported to refineries where it is purified and made into bars or coins
transported to an already mined out area or a specially arranged accumulation site ⇓ 3 Extraction of Ore/Coal Target ore/coal is extracted by a suitable method as in the overburden removal The ore/coal extracted is transported to a crusher by mining trucks then carried to a plant by belt conveyor etc ⇓ 4 Reclamation of Mined Site
The site is approximately 45km east of Newcrest s Telfer gold mine The proximity will enable Havieron to utilise the existing infrastructure and processing plant at the Telfer a move that will reduce the capital expenditure and carbon impact The ore produced from the Havieron mine is planned to be transported to Telfer mine via road
Table 1 lists iron ore production in 2011 12 by mining company and region and Figures 2 and 3 show the location of iron ore mines operating in 2011 12 Figures 2 and 3 also show several mines that either commenced mining operations after June 2012 or did not begin shipping ore off site until after June 2012
