A single CIP tank is fed with 15th of solution with a gold content of 5g/t of solution. The carbon concentration in the tank is maintained at 50kg/t of solution. The eluted activated carbon has a gold content of 80g/t carbon. The adsorption rate is given by d[Au]c1/dt=k(K[Au]s1[Au]c1) with k=0.03h1 and K=10,000. The design target is to produce activated carbon with 500g gold/t and to remove 90% of the gold from solution. The design weight percentage ore in the pulp is 40% and the pulp has a density of 1.4t/m3. Answer the questions below. Note that under steady-state conditions, an overall mass balance of gold across a single CIP tank reactor gives Ls([Au]s0[Au]s1)=Lc([Au]c1[Au]e0)=Mccd[Au]c1/dt a) What is the target concentration of gold in solution? [2 marks] b) What is the required carbon feed rate? [3 marks] c) What is the design mass for the carbon? [4 marks] d) What is the design mass for the solution? [3 marks] e) What are the required residence times for the carbon and for the solution? [2 marks] f) What is the expected mass of pulp in the tank? [3 marks] g) What is the size (active volume) of the CIP tank required
