Study on Recovery of Nickel Sulfate and Cobalt Sulfate from Nickel-cobalt Slag
The 5 000 t/a electrowinning copper production line of a non-ferrous smelting enterprise is in idle state because of insuffi-cient raw materials.This project takes battery grade nickel sulfate and cobalt sulfate as the raw materials of ternary material precur-sors with higher added value,which not only can obtain more abundant profits,but also can capture the market of new energy materi-als encouraged by the national industrial policy,at the same time,nickel and cobalt can be recovered at lower cost,and the compre-hensive utilization of solid waste can be realized.
