This will be the theme of Rob Morrison's keynote lecture at next year's Physical Separation '15 conference- "Reducing energy consumption in comminution by doing much less of it!"<br />MEIhttps://www.blogger.com/profile/14834780351452765156noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-46566958465783590592014-11-12T13:34:10.308+00:002014-11-12T13:34:10.308+00:00If we accept that the ever larger tonnages of ever...If we accept that the ever larger tonnages of ever lower grade ore also require ever larger volumes of water, then machine sorting of dry ROM ore (to reject below cutoff grade rocks) prior to mineral dressing should become a priority.<br />Gus Van Weert, CanadaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-63485054412578984942014-11-11T16:56:54.775+00:002014-11-11T16:56:54.775+00:00From the abstract of the water footprint article, ...From the abstract of the water footprint article, I think it's a good thing a study is quantifying the effects of water usage in the minerals industry, as it does make it easier to analyse and seek ways to optimise water usage. <br /><br /> It was interesting to learn saline water helped with coal recovery, but then saline water helps with leaching for some types of minerals. Although I'm curious about the possible effects the salt will have on downstream processes (effects from more iron ions in solution, corrosion, changes in efficiency, ect), final products and treatment when it comes to releasing that water to the environment. <br /><br />Kate Siew, AustraliaAnonymousnoreply@blogger.com
