However, compared with jinchuan ore - bearing intrusion, jianchaling ultrabasic intrusion formed by magma simple emplacement, and magma fractionated weakly with lower content of nickel and sulphur.
The dissolution of ore, oxidization of sulphur, interference of coexisted elements, conditions of elution are groped.
对矿样的溶解、硫的氧化、共存元素的干扰、洗脱条件亦作了研究。

The effects of magnetic treatment on flotation behavior of primary porphyry copper-sulphide ore and high sulphur secondary copper-sulphide ore were investigated.
