The results of these studies, made on a large variety of ores, was to show in all cases a partial extraction of gold. This extraction varied from 20 per cent, to 95 per cent. While it was always easy to make a partial extraction of the gold, it proved difficult, and in many cases impossible, to get anything like a complete extraction.

Extraction of metals & reduction. The Earth's crust contains metals and metal compounds such as gold, copper, iron oxide and aluminium oxide. Useful metals are often chemically combined with other substances forming ores. A metal ore is a rock that contains enough of the metal to make it worthwhile extracting
