2020-7-23 · The grinding mill might be the issue. Of course, the hydrocyclone isn’t the only place to look when you are reviewing the classification of your grinding mill circuit.. Often when we’re investigating a mill circuit, there are cases where the amount of new feed to the plant has exceeded the ability of the mill to grind
Lead Mentor: Brent Sullivan, Senior Metallurgist Challenge Description Mt Keith was originally designed as a 6 Mt/a concentrator in 1994. Subsequent expansions and upgrades have taken the nominal throughput to 10.5 Mt/a, however the circuit can rarely maintain a feed rate that matches that. Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade ...
