8 Types of Gold Ore Properties and Ways to Process · 1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.
The Silver Extraction ProcessThe Silver Extraction Process. The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silverbearing and is known as Argentiferous Galenite (formula ()S ) and the lead obtained from this ore .
