1. Crushing and screening: the mined copper sulfide ore is sent to the jaw crusher by the feeder for coarse crushing. The conveyor sends the coarsely crushed coppernickel sulfide ore to the cone crusher for secondary crushing. The screening equipment screens the copper sulfide ore after the secondary crushing process, and the qualified ore particles can be directly sent to the next milling link.
This study focused on the preparation of highgrade ferronickel concentrate, the behavior of efficient migration and the polymerization of ferronickel particles during reduction roasting, by adding calcium fluoride and a ferronickel concentrate to lowgrade laterite ore from Yunnan.

An autogenous mill of ID m and an effective grinding length of m was fed with ore of SG to 20% of its volume. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed. The solids in the mill charge were at 80% solids. Estimate: 1.
The milling process for uranium is similar to that used for other metals such as copper, gold or nickel. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks to separate the uranium from other minerals in the host rock.
Tailings: Milling uranium ore produces tailings. Tailings are what is left over once the uranium has been removed from the ground rock and resemble fine sand. They contain longlived radionuclides (such as thorium230 and radium226) produced from the decay of uranium, as well as trace metals like arsenic and nickel.
