Ores are rocks containing enough metal to make it economical to extract. We can extract the iron by reacting the iron oxide with a reactive element.Oct 28, 2016 When the ore was dehydrated by roasting in reverberatory furnaces the extremely fine particles of gold were agglomerated, and between 80 and 90 per cent, could then be extracted by amalgamation, the remainder being presumably coated by oxides of iron. The richness of the ore, however, made even this result unsatisfactory, and a process of chlorination was adopted in practice.Nov 26, 2012 Method 1.
