The process called gold cyanidation makes gold water soluble and thus easier to isolate from the ore While using cyanide allows for the profitable extraction of gold from low quality ores it.Now the gold is soluble This method of making soluble gold is known as leaching In the process of leaching a dilute form of sodium cyanide is added into the ore containing the gold Since gold is soluble after the leaching process it is free to move through the membrane while the rest of ore cannot pass through the membrane Lime is added.
