RECOVERING COBALT FROM SECONDARY SOURCES IN INDIA

In the latter half of this decade, the demand for cobalt in India has increased sharply-from 55 tonnes in 1995 to more than 500 tonnes in 19 98. As India does not have domestic cobalt feedstock sufficient to mee t most of this demand, ii imports and processes considerable secondary cobalt resources. To most effectively deal with these secondary mater ials, Indian laboratories have developed a variety of customized appro aches for recovering cobalt values.
