  • Radioactive Waste From Uranium Mining and Milling

    Mar 02, 2020  Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium The uranium is then separated from the chemical solution, solidified, dried and packagedSurface mining Surface mining is exactly what the word says digging rocks out from the surface, forming a hole or pit In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal Surface mining is also known as open pit or open cast miningCrushing and milling Mining of mineral resources SiyavulaThe jaw crusher has been a staple of the hardrock mining industry since its invention It is used as a primary crusher for all types of ores The jaw typically takes the larger run of mine product and produces a sized discharge for feed to a secondary crusher such as a cone crusher, ball mill, or hammer millMining/Ore Milling Mt Baker Mining and Metals
