A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold .
Most gold mined in Australia today cannot be seen in the rock, it is very fine grained and mostly has a concentration of less than 5 grams in every tonne of rock mined. The feasibility of mining low concentrations of gold largely depends on the price of gold. Gold is bought and sold every day on international gold markets.

These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and costefficient process designs.
The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise.

The Many Rewards of Finding Gold. Anyone who pans for gold hopes to be rewarded by the glitter of colors in the fine material collected in the bottom of the pan. Although the exercise and outdoor activity experienced in prospecting are rewarding, there are few thrills comparable to finding an assay report showing an appreciable content of gold in a sample obtained from a lode deposit ...
About 15 percent of the gold produced in the United States has come from mining other metallic ores. Where base metals such as copper, lead, and zinc–are deposited, either in veins or as scattered mineral grains, minor amounts of gold are commonly deposited with them.
The refiner takes either the sample or the entire portion of gold and mixes it in a crucible with a flux (soda or borax) and lead or silver. The flux lowers the melting temperature of gold, making the process somewhat easier to complete, and the lead helps to collect the pure gold from the alloy. The Refiner Heats the Sample
