The mining solution dissolves the uranium as it travels through the ore zone – effectively reversing the natural process that originally deposited the uranium. The mining solution is injected into the ore zone through a series of fourinch cased drill holes called injection wells and pumped back to surface via a similar series of recovery wells.
Radionuclides are radioactive forms of elements such as uranium and radium. They are harmful to humans and can be released into the environment from uranium mining and milling, coal mining, and nuclear power production. Radionuclides may also be naturally present in ground water in some areas. Radionuclides can contaminate private wells through ...
After mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock.

This Environmental and Social Risk Briefing covers Mining and Metals (including Quarrying). Mining is the extraction and development of subsurface solid resources. Core mining and quarrying products are metals and minerals, precious and semiprecious gemstones, building and road materials and industrial nonmetal products.
The pillars are left to support the overlying rock, and the mineral is then cut from the mining face and processed. The purification process begins with crushing the ore, which is then heated to drive off unwanted gases. This transforms the trona into a sodium carbonate. Water is added to this substance, which is then filtered to remove impurities.
