    A quantitative method for silica flux evaluation

    A quantitative method for silica flux evaluation. Abstract In the smelting of copper and copper/nickel concentrates, the role of silica flux is to aid in the removal of iron by forming a slag phase. Alternatively, the role of flux may be regarded as a means of controlling the formation of magnetite, which can severely hinder the operation
