The Gold King Mine wastewater spill in 2015 is one recent illustration of the effect legacy mines have on Indian tribes. The abandoned mine sent a yellow-orange plume of approximately three million gallons of toxic wastewater, containing nearly 540 tons of metals— including iron, aluminum, cadmium, and lead—into the Animas River watershed.

There are two types of exploration drills in service: one that produces cores and the other that produces chips or cuttings. Both drill holes of a relatively small diameter of approximately 1.5" to 4". The difference in the "product" from these drills is illustrated in Figure 3.1.1. Figure 3.1.1: products of exploration drilling.

If the solution is rich enough can be treated by zinc powder and the precipitated obtained (cement) obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10-11.

mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as well.)
