Question $1$:

Suppose a cyclone is being fed with mica $($density $2800k\frac{g}{m}3)$ in the form of a slurry of pulp $($bulk$)$ density $2000k\frac{g}{m^3}.$ The cyclone underflow density is $2400k\frac{g}{m}3$ and the overflow is $1600k\frac{g}{m^3}.$ Using this information and the information in the table:

a$-$ Illustrate $-$ via a sketch $-$ the working Principe of the cyclone.

b$-$ Plot the efficiency curve.

c$-$ calculate the d$50($cut point$)$ of the cyclone.

d$-$ For particles diameters of $400m$ and $1000m,$ what is the maximum efficiency that can be obtained?

e$-$
