Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and

The rare earth elements (REE) are not all that rare, with earth crustal abundances ranging from 0.3 to 64 parts per million (ppm) (table 1), compared to some of the more well known elements like gold (0.002 ppm) and copper (55 ppm), for example. However when they were first recognized in the late 1700s, they were believed to be rare

The rare earth elements have become vital to manufacturing numerous high-tech products, which has been accompanied by a large increase in their demand. At the same time, there has been concern by the United States and many other Nations about the near-monopoly of mining, processing, and supply of REEs from one Nation, China.

With no need for hard rock mining, crushing and milling, the cost of moving material from the stacks for re-processing will be much lower than those normally associated with mining a primary orebody. Cost of beneficiation to a mixed rare earth carbonate expected to be significantly lower than for a mined mineral rare earth project.

The PUG Plant is designed to remove barren rock from the ore and thereby increase the concentration of the rare earth minerals, producing a mineral pre-concentrate. The PUG process employs a series of crushing, washing, screening, and magnetic sorting methods to concentrate the rare earth-bearing fines and reduce the associated physical mass.
