The main aim of this work is to study the recovery of copper sulfate from mine waters at the Mining Company Bor. For the copper sulfate recovery was treated 91 m 3 Underground mine water, containing 0.3 g/l copper, 2.2 g/l iron at pH 3.2 and 37 m 3 Cerovo mine water, containing 0.5 g/l copper, 0.61 g/l iron at pH 4.5. The mine waters were mixed and prepared 128 m 3 mine solution (copper content 0.35 g/l, iron 1.74 g/l, pH 3.8), then are pre-treated chemically a nd physically for recovery pregnant solution.
