Copper (Cu) is one of the most useful metals. About 15 million metric tons per year of copper metal is produced from the mining and processing of copper ores, typically containing only about 1% Cu. About 80% of the world''s primary copper is produced from ores containing copper-iron sulfide minerals, predominately chalcopyrite (CuFeS 2 ).
· The composition of tailings is directly dependent on the composition of the ore and the process of mineral extraction used on the ore. Certain types of extraction process, like heap leaching for example, may result in quantities of chemicals used to perform the leaching remaining in the material once leaching has been completed.

The rising price of uranium has led uranium producers to increase their plant capacity. The new project proposed to increase capacity is based on processing low-grade uranium by heap leaching. It is necessary to modify the plant, particularly the solvent extraction unit, to handle the increased flow.
Gold | Geoscience Australia
Native gold, R30017. Source: Geoscience Australia. Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold.
Uranium Heap Leaching
In some cases, uranium is extracted from low-grade ore by heap leaching. This may be done if the uranium contents is too low for the ore to be economically processed in a uranium mill. The crushed ore is placed on a leaching pad with a liner. The leaching agent (alkaline, or sulfuric acid) is introduced on the top of the pile and percolates ...

How Drip is Applied in Mining. This drawing shows a typical layout of drip irrigation on a leach pad. The leaching solution is supplied to individual cells by lay flat hose.Often a pressure regulator is installed after the hose fitting to insure that the emitters operate at exactly the correct pressure, which results in the right application rate of solution.
