In line with low grade nickel and dropping recovery rate by traditional flotation method, this paper experiments on CH 12 as a new collector. The nickel recovery rate reaches 90.43 % when the powder grade is 76 % for the super fine powder of -0.074 mm. The results show that CH 12 is effective for nickel flotation. Using the depressor of CMC to depress the vein stone the …

Mondo Minerals owns talc mines in Finland at Sotkamo and Vuonos. A by-product of their talc mining operations is a high-grade sulfide concentrate containing pyrrhotite, pentlandite, pyrite, gersdorffite and magnesite. Nickel is the main metal of economic interest, but the concentrate also contains a small amount of cobalt and a significant quantity of arsenic.

This paper deals with the prediction of locked cycle flotation results from data developed from individual batch tests. A postulate is made that the distribution of material in a separation stage is determined by the chemical conditions and the flotation time and that this distribution can be characterized by split factors which are constants for a fixed set of conditions. With this …
