Mabapi le Theknoloji ea Merafo:
1. Theknoloji ea leaching
Hajoale ts'ebelisong ea koporo ea boemo bo tlase, borale ba khauta, lejoe la uranium le sebelisitsoe haholo ho theknoloji ea leaching, leaching in situ leaching, heap leaching le in situ crushing leaching mekhahlelo e meraro.United States, Canada, Australia le linaha tse ling li sebetsana le 0.15% -0.45% low grade copper ore, copper oxide ore ho feta 2% le 0.02% -0.1% ore ea uranium ha e le hantle ke qubu ea leaching le in situ blasting leaching recovery.

2.Theknoloji ea merafo e tebileng
Ka lebaka la keketseho ea mehlodi ya merafo, mehlodi e ya fokotseha mme dithekenoloji tse batlang di sa teba tsa merafo e tebileng di batla di le ngata haholo.Tšehetso ea theknoloji ea merafo e tebileng e phahame.Ha botebo bo ntse bo teba, mathata a thulaneng le ona a ntse a eketseha, Keketseho, mathata a ho ntša metsi le moea, ho eketseha ha mocheso oa majoe.Matsatsing ana, botebo ba merafo ea merafo e seng ea mashala naheng ea rona ka kakaretso ha bo fete 700-800m, empa lilemong tsa morao tjena ho entsoe li-depositi tse nang le botebo ba hoo e ka bang 1000m.

3.Moepo o bohlale o ka tlas'a lefatše
Nts'etsopele ea mahlale le thekenoloji, lebelo la maiketsetso le salletse morao haholo ho mochini o bohlale, ka lebaka la ts'ebeliso ea lisebelisoa tse bohlale, ho etsa hore katleho ea merafo e eketsehe haholo, ho fokotsa kotsi e ka bang teng ea polokeho.Ka lebaka la matsete tsamaisong e bohlale ea merafo ea tšepe, tsamaiso ea merafo le basebetsi li tlameha ho phethoa.Litsamaiso le lisebelisoa tsa merafo tse ikemetseng le tse bohlale ke tsa bohlokoa ho netefatsa hore merafo e bolokehile ebile e sebetsa hantle.
