How is gold mined?

Gold mining involves several stages and techniques, which can vary depending on the geological characteristics of the deposit and the scale of the operation. Here's a general overview of the typical processes involved in gold mining:

Exploration and Discovery:
Before mining can begin, geologists must identify areas with the potential for gold deposits. This involves conducting geological surveys, analyzing rock samples, and using various exploration techniques such as drilling, remote sensing, and geophysical surveys.

Resource Estimation:
Once a potential gold deposit is identified, geologists estimate the size, grade, and economic viability of the deposit. This involves further drilling and sampling to delineate the extent of the gold mineralization and determine its characteristics.

Mine Planning and Development:
Before mining operations can commence, detailed mine planning and development activities are undertaken. This includes designing the layout of the mine, determining the optimal mining method, and obtaining necessary permits and approvals from regulatory authorities.

Open Pit or Underground Mining:
Gold deposits can be mined using either open-pit or underground mining methods, depending on the depth, shape, and size of the deposit.
Open-pit mining: Involves excavating large quantities of ore from the surface using heavy machinery, such as bulldozers, excavators, and haul trucks. This method is typically used for shallow deposits or where the ore body is located near the surface.
Underground mining: Involves tunneling underground to access the gold-bearing ore. Underground mining methods include drift mining, shaft mining, and cut-and-fill mining, depending on the geological conditions and the size of the deposit.

Ore Processing:
Once the ore is extracted from the mine, it is crushed and ground into smaller particles to liberate the gold particles from the surrounding rock. This process is typically carried out using gold crushers and mills.
The resulting crushed ore is then processed using various techniques to extract the gold. Common methods include gravity separation, flotation, cyanidation, and carbon-in-leach (CIL) or carbon-in-pulp (CIP) processes.

Gold Refining:
After the gold is extracted from the ore, it undergoes further refining to remove impurities and produce pure gold bullion or gold ingots. This typically involves smelting the gold ore to separate the gold from other metals and refining it through processes such as electrolysis or chemical precipitation.

Environmental Reclamation:
Throughout the mining process, environmental considerations are important to minimize the impact on the surrounding ecosystem. After mining operations are completed, land reclamation and rehabilitation efforts are undertaken to restore the area to a stable and environmentally sustainable condition.

Gold mining is a complex and highly regulated industry that requires careful planning, management, and adherence to environmental and safety standards. Additionally, advancements in technology and sustainable practices continue to shape and improve the gold mining process.

Big discovery: 125 kilometers of gold mine

Several gold mines have been discovered in Saudi Arabia. The gold mine is 125 kilometers long. This gold mine is the largest gold mine in the world.

Saudi Arabian National Mining Company has discovered multiple gold deposits extending 125 kilometers south of the Mansoura Masala gold mine. This gold mine is a world-class gold mine. The UAE's "The Nation" said the gold mine is the first major discovery in the exploration plan launched by Saudi Arabia's National Mining Company in 2022. The world-class gold mine has made his already wealthy life in Saudi Arabia even richer.

According to the UAE's "National" report, the extent of the newly discovered gold reserves has yet to be estimated.

Abroad, one comment received widespread approval, "Why is God so generous to them, first with oil and then with gold?"

In fact, in terms of reserves and production, Saudi gold is still difficult to rank among the top in the world.

In terms of individual gold mine reserves, Russia’s largest gold mine Sukhoi Log has gold reserves of 40 million ounces, and South Africa’s South Deep gold mine has gold reserves of approximately 32.8 million ounces, which are nearly the same as Saudi Arabia’s Mansoura Masala gold mine. 6 times and nearly 5 times.

This news caused widespread discussion around the world. These discussions seem to be louder than in Saudi Arabia. Everyone is envious of Saudi Arabia.
"This new discovery could be significant due to the high gold content in the mine," said Nasser Saidi, Lebanon's former economic minister and deputy governor of the central bank.

But a country discovering a gold mine is two different things than a person picking up gold. And the Saudis know that digging for gold is not as profitable as digging for oil.

But here comes the problem. How should they mine gold after it is discovered? Which crusher can mine gold? But this is a professional field. This requires professional people to answer.

Professional friends are welcome to express their professional opinions.

Can jaw crusher mine gold?
