Cycladex

It is a leaching process that uses two reagents (i.e., proprietary) to extract gold from the ore. After crushing, the feed material and the leaching solution are added into a tank and stirred, for about an hour. This is followed by filtering to separate the ore from the pregnant solution. The solution is added into a column with resin, which separates the gold and silver as the target minerals .
