P.S. It is in mineral processing. Thanks

Given the following data from a zinc flotation bank: Table 1: Zinc Rougher data for Assignment 2. Note the particle size is in mesh; Wt\% denotes weight percent of a particular stream 1. Calculate the overall Zn assay for each stream (2 marks) 2. Calculate the size-by-size recovery (4 marks) 3. Plot Rx,zn vs x using the midpoint of the size range as x. (Note: to calculate x first convert mesh to m, take x as the arithmetic mean of the range and plot the x 's on a log-scale). Take a top size of 40 mesh, i.e., 100% of the material passed through a screen of 40 mesh. (2 marks) 4. What is the total zinc recovery? (2 marks) 5. Presentation, including showing example calculations (equations numbered) and providing captions for any figures or tables that you present
