Remark 1:Metallurgical will take use of chromite ore or concentrate, when pyrogenic process smelting ω(Cr2O3)/ω(FeO)>2, but wet process smelting is not limited. ω(SiO2)≤8%(Using ore thermal method for smelting high-carbon will also not be limited.)
Remark 2:Refractory chrome ore and concentrates,ω(SiO2)≤10%,ω(CaO)≤3%,ω(FeO)≤14%
Remark 3:Chemical chrome ore and concentratesω(SiO2)≤8%,ω(A12O3)≤15%。
Remark 4:Diabase with chrome ore,ω(Cr2O3)≥(10%~20%),ω(SiO2)<10%。
Remark 5:The total amount of platinum group elements associated need to choose chromite (0.3~0.4)×10-6, should be assessed.
Remark 6:The selection of lean ore or cut off grade is generally twice the tailings grade.
Remark 7:The min mining thickness of bonanza : single seam 0.5m, complex seam for each monolayer is 0.3m.
