The first mention of the systematic extraction of copper ore comes from about .... in copper processing are towards methods and equipment that use less energy... Amino Acids Key to Gold Extraction Method Curtin Univ. scientists have developed a gold and copper extraction process using an amino acid–hydrogen peroxide system that could provide an environmentally friendly and cheaper alternative to conventional methods.. Prof. Jacques Eksteen says this process should make many low-grade copper-gold leases throughout Western Australia . Processing of copper anodic-slimes for extraction of ... The proposed hydrometallurgical process consists of two leaching stages for the extraction of copper (H 2 SO 4 –O 2) and silver (thiourea–Fe 3+), and pyrometallurgical treatment of the remaining slimes for production of Pb–Sn soldering alloy. Factors affecting both the leaching and smelting stages were studied.    Read More
