CHAPTER – 2 SOLVENT EXTRACTION

Solvent extraction is one of the most extensively studied and most widely used techniques for the separation and pre-concentration of elements [67-69]. The technique has become more useful in recent years due to the development of selective chelating agents [70-73] for trace metal determination. With proper choice of extracting agents, this Get price

Gold processing

The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the 10th century. Get price
