Mining in the Philippines began around 1000 BC. The early Filipinos worked various mines of gold, silver, copper and iron. Jewels, gold ingots, chains, calombigas and earrings were handed down from antiquity and inherited from their ancestors. Gold dagger handles, gold dishes, tooth plating, and huge gold ornaments were also used.
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.
Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground.

Mining was Zimbabwe's leading industry in 2002, contributing 27% of export trade. The chief minerals were coal, gold, copper, nickel, tin, and clay, and Zimbabwe was a world leader in the production of lithium minerals, chrysotile asbestos, and ferrochromium, with more than half of the world's known chromium reserves.
of water (a process called ‘hydraulic mining’) are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains.

Gold extraction refers to the processes required to extract gold from its ores. leading to a boom of investment as larger gold mines were opened up. The parting of gold from silver has been done since ancient times starting in Lydia in the 6th century BC.
INTRODUCTION TO MINING gold rushes that led to the settlement of California,Alaska,South Africa, Australia,and the Canadian Klondike—were achieved with minerals provid-ing a major incentive Mining is never properly done in isolation,nor is it an entity in itself.
Opening a mine and separation plant can cost from $500 million to $1 billion, depending on the location, element, ore grade, and a variety of other factors (Schuler, 2011). Below is an economic feasibility analysis for opening new mines and refineries based on the price of the element (which is driven by demand for that element).
Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the “pay-streak”. Pay-streaks always form along the gold path where the river’s flow slows down on a large scale during a major flood storm.
The Mines and Minerals Act Chapter 21:05 is the law for the mining industry in Zimbabwe. There are other Acts and Regulations that draw their existence from this Mines and Minerals Act. The Act has been acknowledged as a good piece of legislation by both local and international investors.
