What all are the steps involve from metal ore to synthesis of battery grade sulphates to make NMC cathode materials for Li-ion battery?

We know metal (Ni, Mn, and Co) sulphates are used to synthesis of NMC cathode powders. But what are the precursors for synthesis of these sulphates? Is it pure metal we recover from the ore then...
