PAPER OPEN ACCESS
Abstract. A platinum mine in South Africa is a deep mining mine that the mining design involves a series of difficult problems, such as high stress, high temperature and high lifting and so on. Choosing the right mining method and developing system is the key technology to solve these problems, and is also an important plan for mining design.Introduction: Platinum is typically found in nature as a rare mineral, but it is more commonly obtained as a byproduct of other metal mining, particularly from ores containing nickel and copper.It is a dense, malleable, and highly corrosion-resistant metal, making it valuable for various purposes, including jewelry, catalytic converters in Platinum : Properties, Uses, Occurrence and Localities Geology

The effect of the design of a secondary grinding circuit on platinum
Platinum is a major source of revenue to the mining sector in South Africa. Currently, most circuits treating UG-2 platinum ores involve two stages of grinding and flotation. Primary grinding usually involves a ROM ball mill, followed by flotation, secondary ball-milling of the flotation tails, and secondary flotation.A detailed survey of global platinum group element (PGE) resources in 2010 reported that 70.9% of the world’s PGE resources are within the Bushveld Complex, of which UG2 ore contributes about 60% (Mudd, 2012). There are seven Platinum Group Metals in this ore body, i.e. Platinum, Palladium, Rhodium, Gold, Ruthenium, Iridium and Osmium.Effect of Using Different Grinding Media on the Flotation Performance

The estimated annual average prices of palladium, platinum, and ruthenium increased by 18%, 35%, and 88%, respectively, compared with those in 2020, and the estimated prices for rhodium doubled and iridium more than tripled.Palladium (Pd) is a chemical element with the atomic number 46 and the symbol Pd on the periodic table. It is a rare and lustrous silvery-white transition metal that belongs to the platinum group metals (PGMs), which also includes platinum (Pt), rhodium (Rh), ruthenium (Ru), iridium (Ir), and osmium (Os). Palladium was discovered in 1803 by Palladium (Pd) Ore Geology, Mineral, Occurrence, Deposits
