The ionic rare earth (RE) ore body undergoes particle transport and pore structure change during the leaching process, resulting in "uneven percolation, preferential channel, leaching blind area," and other problems, leading to structural changes in the ore body, low leaching efficiency, and waste of resources. The unsaturated infiltration process is also the key stage that causes these problems.

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,60012,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rareearth minerals are monazite and bastnäsite (Figure 1ab and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REEbearing monazite is a complex phosphate. 5 Bastnäsite, also known as bastnaesite and bastnasite, is a fluorocarbonate.
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2.
It was also determined that mill recoveries and concentrate grade increase with increasing mill head grades . References. ↑ S. McKinnon, "MINE 448 Notes: Ore Value," Kingston, 2019. ↑ A. Nieto and K.

The silicatebased ore rich in rareearth elements was supplied from a Canadian site (primary ore). The particle size distribution was measured by sieves 45, 75, 125, 212, 300, 425, 600, 850, 1180, and 1700 µm in size. Quantification of the main elements was carried out in Xray fluorescence (XRF, PANalytical Epsilon 3 XL, Malvern, UK).
