what is the formula for specific gravity?Mineral processing unit operations handle slurries with a variety of properties. Slurry density as

an important characteristic can be expressed in different ways depending on the processing stage.

a$)$ Suppose that bastnaesite based a rare earth ore processing plant involves the treatment of

slurries at $36\%$ solids by weight. Express this density in terms of kg per litre $($i$.$e$.,$ tonne$/$m$3)$

if the average SG of the dry ore in this slurry is $2\mathrm{.}92$

b$)$ What is the value of corresponding $\%$ solids by volume for this slurry, which is important

for the design of hydrocyclone systems?

c$)$ How much fresh water is to be saved in m$3$ per year if $65\%$ of process water is recycled at a

steady state operation treating $5000$ tonnes of dry ore$/$day $($consider $350$ days of operating

days in a year$)$ following dewatering of the products in the final stages of the process?
