Pearson s Metals mines two ores R and S. The company extracts minerals A and B from each type of ore. It costs 50 per ton to extract 80 lb of A and 160 lb of B from ore R. It costs60 per ton to extract 140 lb of A and 50 lb of B from ore S. Pearson s must produce at least 4000 lb of A and 3200 lb of B.
When you mix the finely powdered goldbearing rock with some mercury the gold within the rock dissolves to form what s called a gold amalgam. The next step in the process is to separate the gold amalgam from any unreacted mercury. We did this by squeezing the crude amalgam through a small piece of chamois leather.

Gold ore associated with Telluride is hardly soluble in ordinary cyanide solutions and special treatment is necessary for its extraction. There are two methods in use in such cases. The following is an extract from a paper by E. W. Nardin of the Hannan s Star Mill Kalgoorli published in the Mining and Scientific Press of October 24th
Apr 9 2022The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metalimpregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Karat is a measurement unit to indicate how much pure gold is present in an alloy. For instance 24karat gold
Nov 28 2021I have been extracting gold from ore for some time now. I buy ore (dirt) containing gold from a person then I crush it to very small pieces and then put it in cyanide bath. I then drain the bath and add activated carbon which absorbs the gold I burn the carbon and get the gold. I buy the ore at a high price and I m barely profitable.
