Process Of Gold Mining In Super Pit Mine Australia

Super pit gold mine is the largest open pit mine

Kalgoorlie mine In Australia or better known as the Super Pit is located off the Goldfields Highway on the south-east edge of Kalgoorlie, Western Australia. Super pit gold mine is the largest open pit mine which has a hole a length of about 3.5 kilometers, 1.5 kilometres wide and 570 metres deep that make up the rectangle.

The Super Pit gold mine is owned by Kalgoorlie Consolidated Gold Mines Pty Ltd, a company owned two joint venture between Barrick Gold Corporation and Newmont Mining Corporation with respective shares of 50%

Kalgoorlie Consolidated Gold Mines Pty Ltd (KCGM) was formed to manage the assets and operations of joint venture partners, Normandy Australia and Homestake Gold of Australia Limited.

MINERAL DEPOSIT IN SUPER PIT GOLD MINE

Mineral deposit in super pit gold mine

Gold deposits Super Pit is one of the richest gold deposits in the world.  Composed of a series of mineralised faults known as lodes, a greenstone belt consisting of volcanic and sedimentary rocks and surrounded by extensive granite. These rocks all belong to the Archaean period of the Earth’s history and the goldfield is between 2.6 and 2.9 billion years old.  the deposit mainly occurs in a host rock known as the Golden Mile Dolerite.

The main host rock for mineralisation the Kalgoorlie district in Super Pit gold mine is the Golden Mile Dolerite, the largest of the dolerites in the area. There are two main styles of mineralisation. The Fimiston Style consists of classic Golden Mile lodes with abundant sulphides and tellurides. The Charlotte Style describes younger white quartz veins which are typically mined at Mt Charlotte, but have been found in other smaller deposits in the Kalgoorlie District.

The Golden Mile lodes have several characteristic orientations, each with slight variations in the style of the mineralisation. More than 1,000 individual ore lodes occur within the Golden Mile, some extending up to 1,800 metres long, 1,200 metres deep and 10 metres wide. They are all within an area over five kilometres long, two kilometres wide and more than one kilometre deep. The highest gold grades are typically associated with gold tellurides and alteration minerals with high vanadium contents.

Batu Hijau mine is process of mining with a large surface mining operation in Indonesia,  the located in the southwest region of the island of Sumbawa, in the District of Sekongkang, West Nusa Tenggara Province in Indonesia.  Batu hijau mine Indonesia originally discovered in 1990 and then commercial mining production began in 2000, primarily producing copper and small amounts of gold and silver.

Mining Project in Batu Hijau mine held by PT Newmont Nusa Tenggara (PTNNT), a company owned by Newmont Indonesia (US, 35.44%); Nusa Tenggara Mining Corporation (Japan, 27.56%), PT Pukuafu Indah (Indonesia, 20%) and PT Multi Daerah Bersaing (Indonesia, 17%) with system  contract of work and Newmont as the project operator.

MINERAL DEPOSIT IN BATU HIJAU MINE INDONESIA

Ore mineral in Batu hijau mine Indonesia

Mineral deposits in the mines Batu hijau is a porphyry copper deposit containing small amounts of gold and silver ore

These Porphyry copper deposit are overwhelmingly hosted by composite stocks of diorite to quartz-diorite and, to a much lesser degree, more felsic compositions such as tonalite and monzogranite.

Mineral deposits tend to be characterised by a strong correlation between the distribution of copper sulphides (chalcopyrite and bornite) and gold as the native metal in addition to having a notably higher magnetite content. Gold typically occurs as minute (<10-15 micron) inclusions in the copper sulphides.

Porphyry copper deposit is indeed very typical deposit found in the Southeast Asian region. These porphyry deposit is one in which the valuable metals are not immediately available and require processing since they are mixed with rocks and minerals that are not economical to process.
