On February 27, 1980, the Minister of Mines had announced a sevenyear moratorium on the recording of mineral claims for the purpose of uranium exploration and the development of uranium deposits on existing claims.
Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
· Uranium: Powering the Cleanest Source of Energy. The world's energy needs are growing with its population. However, achieving a netzero carbon economy while meeting our growing energy needs requires a larger role for clean, sustainable, and reliable sources.

· Uranium is a heavy metal, so heavy it sometimes gets used in keels of yachts and as counterweights for aircraft control surfaces. It is the key to nuclear power generation. It's times as dense as water, has a melting point of 1132 degrees celsius, and is primarily found in Australia, Kazakhstan, and Canada.
Europe is also a leading source for depleted uranium exports given its % worldwide share, trailed by North America at % and well ahead of Oceania (%) mostly Australia, then Asia (%).

· Refractory uranium ores from Canada and Australia containing brannerite and davidite required grinding to 55–65% passing 200 mesh for the uranium minerals to be sufficiently liberated. Several researchers have investigated the effects of finer grinding of brannerite ore on the uranium extraction during leaching, and the conclusions appear inconsistent.

In the early years of uranium mining after World War II, the mining companies often left sites without any clean up after the ore deposits were exhausted: often, in the United States, the mining and milling facilities were not even demolished, not to mention reclamation of the wastes produced; in Canada, uranium mill tailings were often simply dumped in one of the numerous lakes.
