| titleOfInvention | Acid wastewater in mine recycling and deep-purifying method |
| abstract | The present invention relates to a kind of acid wastewater in mine recycling and deep-purifying methods, include the following steps：(1) acid wastewater in mine adjusts pH value by neutralizer and recycles gypsum；(2) iron is recycled by two sections of neutralizations again；(3) high performance vulcanization reaction recycling copper zinc is carried out；(4) copper and zinc are separated after copper cadmia Ore Leaching, obtains solution of zinc sulfate and copper-rich slag, and recycle vulcanizing agent, and solution of zinc sulfate prepares zinc sulfate by the way that MVR technology is dry, and vulcanizing agent is back to step (3) and carries out high performance vulcanization reaction；(5) effluent reuse or qualified discharge after advanced treating.This method is to the recovery efficiency of copper in acid wastewater in mine up to 85% or more, 95% or more the rate of recovery of zinc, it can produce the gypsum of high-purity simultaneously, opposite traditional technology reduces the quantity of slag up to 20% or more, realize the recycling of acid wastewater in mine, new technology purification is efficiently, at low cost, has significant economy and environmental benefit. |
