A refractory gold ore has mostly a pyritic gold mineralogy with an overall grade of 2.23g Au per tonne. The recovery process involves two stages. The first stage involves the concentration of gold-bearing fraction into 4.42% of the ore crushed. Tailings from this first stage shows the following in its size fractions Subsequently, the concentrate is treated with a pressure oxidation process which allows a stage recovery of 95.53% gold recovery. a) Provide a block diagram of this process showing the mass flows with appropriate labels (e.g., overall assays and mass values) b) What is the Au assay of the overall tailings and the gold recovery in the first stage? c) What is the overall gold recovery based on the first and second stages combined
