the grind increasing the m value. True flotation of non-sulphide gangue NSG only occurs due to attachment to molybdenite the very low Mo grade of the ore results in very low NSG R max values. As a comparison copper porphyry ore may exhibit NSG R max of 4 to 8. The molybdenite recovery was generally poor under the standard size .

Alternatively with a grind of 70 -200 mesh . and 0.06 kgtonne of pine oil a bulk rougher float analysing 20.8 Cu 0.41 Ni and 26.3 S with respective recoveries of 96.4 43.0 and .

Copper Flotation 911 Metallurgist

May 16 2016 Porphyry copper ores usually medium to medium hard require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate thus some form of regrinding is necessary on the rougher flotation copper

Copper Sulfide Flotation 911 Metallurgist

Apr 13 2016 Copper Ore Grinding Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.

the ore input goes into the tailings which are stored in large dams near the mine and are used for water recycling to the flotation stages. Separation of special copper ores such as those containing molybdenite or with high zinc or lead content Canada is also possible by flotation methods. Flotation of non-sulfide copper minerals is

The Ore Grade And Depth Influence On Copper Energy Inputs

Nov 22 2016 The study established an input for beneficiation to a 75- m grinding size plus smelting at 72 131 and 249 MJkg of copper for 1.0 0.5 and 0.25 ore grades respectively. The evaluation for beneficiation to a 5- m particle size was established at 129 244 and 474 MJkg.
