  • gold cyanide processing from granite

    Plant gold extraction cyanide process. Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. Get PriceОнлайн-запрос
