A. Gorosi rinogamuchirwa rinofanirwa kusangana nemimwe mwero, senge hunyoro, kuwanda kwehuwandu uye kusvibiswa kunofanirwa kuzadzisa zvinodiwa zvegiredhi rinoenderana rezviyo mbishi.
B. Kucheneswa kwekutanga kunobvisa tsvina huru, zvidhinha, matombo, tambo mugorosi.
C. Kucheneswa kwegorosi kunobvisa tsvina yakakura (mashanga egorosi, madhaka), tsvina shoma, ivhu reraimu, jecha, nezvimwewo.
D. Kuongorora mhepo kunobvisa huruva nehundi yegorosi.
E. Magnetic separation inobvisa maginetic metal tsvina kubva pagorosi.
F. Tsanga mbishi ichaiswa mudura regorosi mushure mekucheneswa kwekutanga.

Sangana neinotevera chiyero mushure mekuchenesa:
(1) Bvisa 1% yetsvina yakakura, 0.5% yetsvina diki uye ivhu reraimu.
(2) Bvisa 0.005% yemagineti simbi tsvina muzviyo mbishi.
(4) Bvisa 0.1% yekusvibiswa kwechiedza nemhepo yekuongorora michina.
(3) Gorosi richasimudzwa rochengetwa mudura regorosi.
(4) Hunyoro hunofanirwa kudzorwa pasi pe12.5%, uye tsanga mbishi inofanira kuongororwa nguva nenguva kuti ive nechokwadi.
