Gold mining is a major economic driver for many countries across the world. Well managed, transparent and accountable resource extraction can be a major contributor to economic growth due to the creation of employment and business opportunities for local people.
Gold and copper are found in ore bodies associated with porphry. Porphry is a general term applied to igneous rocks of any composition that contain conspicuous phenocrysts (crystals) in a fine grained groundmass.

The Meikle mine exploits one of the world's highest grade Carlin type gold deposits with reserves of ca. 220 t gold at an average grade of 24.7 g/t. Locally, gold grades exceed 400 g/t. Several geologic events converged at Meikle to create these spectacular gold grades. Prior to mineralization, a Devonian hydrothermal system altered the Bootstrap limestone to Fe rich dolomite.
Hi Dai Uy, because at $1781.30 per oz. of Gold @ 2.33 ozs. per Lb. of ore concentrate approx. $636 per oz. of Pd per Lb. of ore concentrate spells $8,300,860 per ton of this type of ore for gold; approx. $839,520 per ton of this type of ore for Pd, plus the Pt 1/5 to 1/4 oz per Lb.
The gold content in these sediments varies from a few tens to 100150 g/m 3, increasing in the sands. The total length of this rich Smolensk Vyatka gold bearing zone extends 1500 km from east to west, with an average width of about 80 km (see Fig. 2 ).

Jean has published more than 50 research papers in international journals, and she was the invited lead author for the Economic Geology 100th Anniversary Volume paper on Carlintype gold deposits. She chaired the 2005 Gordon Research Conference on the Geochemistry of Ore Deposits and was a session chair at the most recent Gordon Conference in 2016.
The standards of high or low grade gold ore are set by the World Gold Council, which is a non profit organization that was established to promote the use of gold and gold products internationally
Primary tasks in economic geological analysis of gold ore deposits are determination of ore formation type and mineralization scale. Therefore the system for characterization of ore deposits should contain parameters necessary for performance of these tasks.

An ore deposit, in its simplest terms, is a portion of the Earths crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical.
If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary dryer or a heated roller mill. manganese ore processing gold gold ore Dewatering Equipment Magnetic
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
For example, as the average gold ore grade has fallen substantially over the past 20 years, the gold mining industry now has to move a great deal more ore to produce the same or even less gold. In order to move a great deal more ore, the mining industry has to spend a lot more on trucks, tires, materials, energy, and labor.
The average gold content of soils is 0.005 ppm, and the average for natural fresh waters is 0.00003 ppm. Sea and ocean waters contain an average of 0.000012 ppm Au. Gold is a trace constituent of many plants and animals.
