High Clay OresA Mineral Processing Nightmare Part 2
processing high clay ores These clay minerals typically form in near surface geological environments due to weathering, particularly above the natural water table, sedimentation and diagenesis and are common in hydrothermally altered rocks Clay minerals associated with alteration is referred to as Argillic alterationwaste dilution from country rock containing clay can adversely affect the process There are some solutions which assist in processing high clay ores but do not negate all of the difficulties The presence of clays has a major influence on the process selection and equipment used in the final flowsheetThe Difficult Mineral Processing Issues with Processing impacts The mineral industry’s understanding of the issues and solutions of clayrelated processing issues remains poor and in many cases the processing problems associated with clays are simply avoided by not processing the ores As operators we approach the problem of processing high clay ores by finding chemical andThe Difficult Mineral Processing Issues with Clay Ores

Mining of ore for heap leaching employs the same techniques and equipment as mining of ore to feed any other process method Where uncrushed ore (runofmine (ROM) ore) is placed on the leach pad, ore may be blasted very heavily in order to reduce rock size and improve gold recovery In highrainfall environments when processing clayrich > Mineral Processing > RESOURCE PROJECTS > TECHNOLOGY > INTEGR > Engineering Design > Training > Specialist ServicesATED SERVICES Heap Leaching > High clay ores require agglomeration with cement in an agglomeration drum and time to cure before stackingThe Difficult Mineral Processing Issues with Processing Processing of high clay ores is usually related to negative effects in particular in the flotation stages A good description was made recently in the work by Chen and Peng (2018), who developed a general review about the mechanisms and behaviour of clays in mineral flotation The background they presented is general and useful for any situation in which clays appear since most of the challenges The effect of clay minerals on the process of flotation
