Nickel and Cobalt Production - ScienceDirect

Production of high-purity cobalt and copper from a purified pregnant Co 2 +, Cu 2 + sulfate solution. A plant that produces about 100,000 tons of copper/year and 8000 tons of cobalt/year has four extraction mixer settlers and two strip mixer settlers. A portion of the raffinate (left mixer settler) goes back to leach for Co enrichment (not shown).

A critical review on toxicity of cobalt and its ...

The cobalt toxicity on growth and metabolism of tomato plants was studied in sand medium at five levels of concentration, i.e. 0, 0.05, 0.1, 0.4 and 0.5 mM. Strong effects of cobalt on tomato were observed at 0.5 mM after 3 days of metal supply. The prominent symptoms were appearance of chlorosis on young leaves followed by necrosis and withering.
