Abstract

The refractory or low grade nickel laterite domestic ores in Republic of Macedonia are investigated by conventional magnetic separation technology or segregation - flotation - magnetic separation, or production and smelting to ferronickel. In the mean time investigations are directed to the new possibilities of leaching by microorganisms - bioleaching. The paper is result of these technologies and investigations carried out for recovery of in the mentioned ores. The average grade from segregation - flotation process as a nickel metal concentrate was cca 80-90% Ni, and recovery was up to 80-85%. The average recoveries from leaching were cca 87-90% for nickel and the average recoveries from bioleaching were cca 93-95% for nickel.
