2017-2-10  —Many of the ores we run would come under the head of “ rich spotty ” ores, as the Colorado phrase is. To crush and cut down such an ore, according to best Colorado rules of sampling, would require breaking the whole batch of from 500 to 1,000 lb. down to 10 or even 30-mesh. This would ruin our gold stamp-mill

Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,

By understanding the ore breakage characteristics and by utilising comminution circuit modelling, the benefits of SAG mill feed size manipulation can be readily assessed. Furthermore the paper discusses the features of partial secondary crushing circuits and the pros and cons of various configurations.

Varvara hub Polymetal

Run-of-mine ore is crushed in batches in a single jaw crusher, with separate crushed ore storage for leach and float material. Gold doré and gold-copper concentrate are produced from the two circuits of the single processing plant. The float ore circuit comprises two-stage milling (SAG mill and ball mill) and conventional flotation.

Mass Blasting for Mine to Mill The AT04 Mass Blast

This means that ore to the mill must be well fragmented from blasting that provides high extraction rates from draw points, with minimal dilution from overbreak or fall off, and sized to maximise SAG mill throughput. The AT04 Mass Blast contained significant ore reserves which were required to meet gold production targets.
