Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding
Barrick Goldstrike Mines is the mother lode for Barrick Gold. The company operates two producing ore mines (the open pit BetzePost and the underground Meikle and Rodeo) on the property, located on the prolific Carlin Trend in Nevada. Goldstrike produces more than million ounces of gold annually and has reserves of about 13 million ounces.
#0183;#32;Mining Processing amp; operations: The Goldstrike complex consist of three distinct mines: the large BetzePost open pit mine, and the Meikle and Rodeo underground mines. The ore from all three mines is milled and leached by the cyanide process. Carlintype gold deposits host gold mainly as microscopically fine grains.
Sedimentary ore deposits include banded iron formations, and gold, platinum, zinc, tin, and even diamondcontaining ores that formed in sedimentary environments. Lastly, ores can form as a result...
Of all the methods of extracting gold amp; processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery
Barrick Gold Corporation has one of the largest openpit gold mines in North America located on its Goldstrike mine property in northeastern 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.

Barrick Gold Corporation has one of the largest openpit 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.
At full capacity, 13,400 tons of ore can be processed daily, with leaching taking place simultaneously in two sets of seven tanks. The thiosulphate process will enable Barrick to contribute an average of 350 to 450 thousand ounces of gold each year to their operation, allowing the large plant to keep operating, preserving jobs and bringing much needed income to the State.
