Surface mining methods an overview Basic Mining

Solution mining is done by dissolution, melting, leaching, or slurrying. Water is injected into the minerals and is pumped out to the surface in solutions. Evaporite minerals like salt and potash are dissolved, sulphur is melted through Frasch process, and other minerals

Heap leaching Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo

In situ leach Wikipedia

In-situ leaching, also called in-situ recovery or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining. The process initially involves the drilling of holes into

Mining Surface mining Britannica

Mining Mining Surface mining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

Learn About the Heap Leaching Process & Mining

Leaching solutions (or lixiviants) used in heap leach mining are either highly alkaline such as sodium cyanide, or highly acidic such as sulphuric acid. To ensure uniform distribution of the lixiviant to the ore heap and to minimize evaporation, drip irrigation systems are the preferred distribution method.

Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out either as heap leaching or insitu leaching.
