COMPARATIVE RESULTS OF COPPER FLOTATION FROM

2013-11-26  Smelter slag is obtained in the process of metallurgical converting of copper concentrate in the Smel-ter Plant in Bor, Serbia. Today, the reserves of this material are evaluated at about more of a year, with the average copper content of 0.6-0.9%. Production of copper concentrate by flotation of smelter slag has started in 2001.
