OPTIMIZATION OF DISSOLUTION OF COPPER FROM A NIGERIAN GOLDFIELDITE ORE FOR INDUSTRIAL UTILIZATION
Conventionally, copper ores are treated and processed by a high-energy intensive pyrometallurgical process. However, the huge amounts of emission of obnoxious gases demand the development of a simple, low-cost, and environmentally friendly technique. In this work, the dissolution kinetics of goldfie...
