  • How Gold Is Made History Used Parts Procedure

    because gold is a finite resource, its long-term future is limited. In the short term, however, it will continue to find widespread use in jewelry and in industrial applications, especially in the electronics field. In the last few years, several companies have focused on extracting gold from sulphide ore rather than oxide ore.from this result, mlg appears to be the most suitable liquidsolid ratio for extracting gold and platinum from the ore sample; i.e addition of about 0.23 of thiourea and 0.15 of sulfuric acid is necessary for complete extraction of gold and platinum from unit gram of the ore sample.

  • What Is Gold Ore Worth High Grade Mining Ore

    extracting gold from this type of ore is feasible for multi-million dollar mining companies, but almost impossible for the average person to do. also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout. So a mine that produces some high-grade ore will also process tons of gold. magnesium. tags: question survey seconds method of extracting metals from their ores that are more reactive than carbon. which statement is correct about extraction of iron from its ore? answer choices iron is more difficult to extract than copper. iron is the easiest metal to extract.
