How to Extract Gold from Rock

Most gold ores are extracted from open mines in an open or underground fashion. This makes it easier to extract different types of ore.

About 65 percent of gold ore in the United States is extracted from open mines, while 35 percent is mined underground.

Prices for extracting and recycling the ore are key factors in deciding which method to choose between underground and open mining. Open mines have a higher cost of extracting and disposing of tailings. This is why the ratio of tailings to ore may be an important factor in comparing extraction costs.

To determine the price of underground and opencast mining, we use the ratio of tailings/ore extracted.

One of the most valuable minerals is gold. Inflation can be controlled by monetary support.

The exploration and identification of gold reserves was a way to eliminate inflation. However, the consequences of this significance will be obvious when the ore is processed and extracted.

Local people still extract gold in many places on the planet. It's then sold as raw gold locally.

This process can be achieved through manual and mechanical processes such as washing (gravity separation), grinding, and mashing.

By passing a mixture of crushed gold ore and mercury-coated copper sheet, incorporation can be achieved.

The gold grain is separated from the cache periodically. However, very fine gold particles cannot be separated using these methods. In many cases, especially in Brazil, a cyanide process has been suggested to extract any remaining gold.

Suppose gold is found in large areas of river sand. Floating dredgers are used to extract the metal. For example, this mining method can be found in Siberia or North America.

Underground Mining

Primary gold ores account for over 90% of all gold ores in Western countries. These ores are mostly mined underground.

Canada and Africa have 100% and 70% of all mines. However, in the United States, only 3.5% of mines are underground, while the remainder is open-pit. It is mined underground, using both ancient and modern methods. The qualities of gold include the following:

  • Exploring and digging
  • Stops for cutting and filling
  • Stop shrinking
  • Sub-level stop
  • Open stops
  • Stops for square sets

Most underground mines are located at shallow depths (1 to 4 kilometers). In South Africa, approximately 250,000 heaps per month are mined. More than 125 km of tunnels are excavated each year, and nearly 8,000 people are employed as miners. This mine has gold veins at a depth between 10 and 30 cm.

High temperatures, rock bursts and mechanical devices are all important issues in underground mining.

Because transport costs can be as high as the extraction cost, removing all waste materials from the mine basement is important.

Chemical Method in Gold Mining

The chemical method uses gold soil to dissolve in acid to create gold chloride. The solution must be filtered after the gold has been dissolved in the acid to remove soil impurities.

The dissolved gold is then precipitated with materials such as sodium metabisulfite. Finally, the gold powder, like in recycling electronic components, is washed, dried, and finally melted. This process is not efficient for many reasons.

Drilling Method in Gold Mining

The formation process involves the addition of flux to gold soil. This may include a mixture of silica (silicon dioxide), washing soap, silver, copper, or boron. It is then melted in an exceedingly potent kiln.

This removes many problematic substances. The silver and molten copper are oxidized and become "slag," and then the coolant cools, which absorbs the gold in the form of a little nugget.

The slag is then separated from the copper or silver alloy, and the alloy is dissolved in the acid to extract the gold.
