Abstract
This research focused on the design of a ferrochrome – slag mechanical separator for a company in Harare, Zimbabwe.
The company’s current production is 420 tonnes of alloy per month. The aim of project is to raise the production from 420 to 500
tonnes of ferrochrome production per month by introducing a mechanical separator at metal recovery plant that produces 80 tonnes.
The difference in specific gravities of ferrochrome and slag is the key principle applied in achieving separation of the two products.
The densities of ferrochrome and slag are 6800 kg/ mand 2800kg/ m respectively hence gravity separation method in water
medium can be done.
