Small Gold ore Crushing Machine. Typically, gold ore crushing machine refers to crushing equipment used in the crushing process of gold-bearing rocks. And main types of small gold ore crushing machine can be divided into the jaw crusher, impact crusher, cone crusher, and gyratory crusher, etc.The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery.
