“The typical benefit of an opHmizaHon study is a 5-‐10% increase in throughput at a given product size. For a more complex circuit, the gains may be more dramaHc.” Mineral Comminu-on Circuits: Their Opera-on & Op-miza-on, JKMRC, Page 332.

If a once-‐off op-miza-on study can result in a 5-‐10 % throughput increase, what would a more con8nuous op8miza8on strategy achieve?

By Minerality


By itself, doing an op-miza-on study will make your mining opera-ons more money, but by following a con-nuous approach you will be saving even more. How much can your opera8ng plants improve?

Improvement range from op=miza=on (USD per hour extra)

For a 2,000 tons per hour Copper Plant you can expect between $2,423 per hour or $4,845 per hour more. For a 5,000 tons per hour Copper Plant you can expect between $6056 per hour or $ 12,112 per hour more.



By Minerality

Even a 1 % improvement in a 2,000 tph plant will result in USD 12,000 improvement per day


A Minerality opHmizaHon package adds value through a combinaHon of three elements:


By Minerality

1. Plant survey & op8miza8on report: For immediate improvements

2. MetSMART op8miza8on soFware to con-nuously increase yield & recovery

3. 3 Day training workshop for process metallurgists

Slurry condi=ons

Slurry pooling or low slurry levels can not be diagnosed by measurement devices. MetSMART can diagnose and solve this. Slurry pooling may drop throughput by up to 10 %.
