(c) The ore being placed on the heap has an average copper grade of 1.0% and the lixiviant addition rate is 900 m3 /hr. 5% of the liquid is lost through evaporation and other loses and the pregnant solution contains an average of 2.1 kg Cu/m³. The solvent extraction stage recovers 90% of this copper, with the barren solution having additional acid and water added to make up for the lost volume and consumed material before being added back onto the heap. What is the average recovery of the copper from the heap leaching assuming no losses in the SX/EW?

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...................................
A 15.00 g sample containing mixed alkali and other inert components was dissolved and diluted to 300 mL with water. A 20 ml, aliquot was titrated with 5.02 mL of 0.5352 M HCI to reach PHP endpoint. Another 20 mL aliquot was titrated to the BCG endpoint, using up 18.87 mL of titrant in the process. Identify the alkali components and their percent weight.
Mganga is doing a routine analysis in a copper plating factory. He is regularly making up solutions of verypure CuSO4.5H2O. He suspect that a batch of a reagent used to make up a stock solution of CuSO4.5H2Ois impure and it may contains some CuCl2. He asked you to determine the percentage impurity as follows:Dissolve1.500g of a mixture and make up to 1.00L mark.150mL of this solution was treated with 20.00mLof 0.100M AgNO3 to remove 98.6% of chloride as AgCl precipitate.
Countercurrent Multistage Washing of Ore. A treated ore containing inert solid sulfate is to be leached in a countercurrent multistage gangue and copper extractor using pure water to leach the CuSO4. The solid charge rate per hour consists of 10000 kg of inert gangue (B), 1200 kg of CuSO, (solute A), and 400 kg of water (C). The exit wash solution is to contain 92 wt % water and 8 wt % CuSO4. A total of 95% of the CuSO, in the inlet ore is to be recovered. The underflow is constant at N Calculate the number of stages required. 0.5 kg inert gangue solid/kg aqueous solution.
The average copper grade of the ore is 0.7 %. The total pregnant solution flowrate from all the leach pads is 8 000 m3/hr, with an average concentration of 1.8 kg/m3, with the concentration of copper in the lixiviant that is irrigated onto the heap being 0.2 kg/m3 (ignore any solution or copper losses to the environment in these calculations). What is the average copper recovery for the process?
The standard addition method is used to analyze a sample of a river water for mercury.

An analyst weighed 0.25045 g of the Buffalo River Sediment reference material.(RM # 8704) to determine Pb levels. The material was digested in an acid medium toBring it to a solution which was made up to the 30.2450 mL mark with distilled water. If thePb concentration in the control certificate of analysis is (150 ± 17) mg / kg, and theanalyst recovered 95%, what was the concentration of Pb in the solution?
Suppose you have a soil that is made up of 10% organic matter with CEC = 200 cmol/kg, 40% kaolinitewith CEC = 10 cmol/kg, and 50% vermiculite with CEC = 100 cmol/kg.1- Calculate the overall CEC of the soil by taking a weighted average of the three soil components.2- What percentage of the overall CEC is contributed by the organic matter? How does that numbercompare to the 10% of the soil itself that is organic?
