b) A plot of land was explored and found to contain 1,000,000 grams of gold. The average goldconcentration was found to be 0.8 grams per ton. A mine was set up on it and sluice boxes were used as the main gold recovery units and recovered200,000 g of gold from 80% of the ore. The concentration ratio of the sluice boxes was 10,000.The field was mined again. On this occasion bowl concentrators were used. The feed used wasestimated to be 800,000 tons and the concentration ratio of this unit was 20,000. 750,000 grams ofgold was recovered. Calculate the following: i) the Quantity and grade concentrate from the sluice boxes .................. ..................... ii) the quantity and grade of the concentrate from the bowl concentrator plant. .............. iii) the quantity and grade of the material remaining at this location...................................
