Problem with gold recovery from sulphide orehow may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. this latter point is most important. in many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an oxidized ore. a neighboring mine may have a higher tailing loss but still make more money due to lower milling costs.
Read MoreFor many years, after introduction of the cyanide process for dissolution of gold, the usual practice was to grind all the ore with little or no concentration before cyanidation. there were two general cyanidation flowsheets sand leaching and all sliming. the latter ultimately has almost completely replaced sand leaching.
Read MoreWith the advent of flotation and the fact that gold either free or finely disseminated in pyrite, etc., could be floated, many possibilities opened up for the treatment and concentration of gold ores. it also provided the means of working ore bodies hitherto considered unprofitable or metallurgically impossible for cyanide treatment. two examples are the large low-grade ore bodies which require very fine grinding and refractory sulphides which have to be concentrated and roasted to expose gold to cyanide action.
Read MoreThere are many arrangements and combinations using flotation in conjunction with treatment of gold ores. the two gold process flowsheets shown, with some variations, are probably the most commonly used.
Read MoreIn goldflowsheet no. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.
Read MoreFlotation concentrates are dewatered and finely ground for maximum exposure of gold and sent to the cyanide plant. the grinding is preferably done in cyanide solution.
Read MoreStandard practice is followed as shown the slight difference usually being more intense agitation as supplied by super-agitators with maximum aeration. the following advantages may be claimed plus others not enumerated
Read MoreWho would think that selective flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized andor admit when it hurts. flotation mass-pull is a process that is often misunderstood a learner8217s mistake made by non-operating types. you do not need to pump anything in the lab.
Read MoreIn selective flotation, less is more over 2 years ago i wrote about the intricacy and importance of mass pull in a plant vs laboratory. i need to restate i suppose that flotation is a process of concentration in which we must put has much metal as possible into as little mass as possible.
Read MoreOn the below chart, selective flotation separation is obtained from the green line 1 mass to the red line 4.5 mass. after gt4.5 mass, you get mass pull, just mass. no selectivity, no concentration. you could float all day and yes get more mass. you could float off the whole tailings if you have enough time.

Read MoreNative gold is a mineral that is easy to float,the crystal structure of native gold is metallic lattice,forming the character of the metal bond.
Read MoreBecause of the weak metal bonding force, the native gold has the characteristics of small surface wettability and easy to float.
Read MoreThe production practice shows that the native gold and many heavy metal sulfide belong to the floating minerals,its easy to be collected by xanthate flotation collectors.
Read MoreHowever, due to the content of gold and other factors, the flotation of native gold has the following characteristics.
Read MoreMost of the native gold in the ore is in the form of fine disseminated,the gold particles must be finely ground in order to achieve the monomer dissociation.
Read MoreGold is often nbspdense associated with sulfide minerals, especially with pyrite,therefore, the sulfide minerals must be selected at the same time in the recovery of gold.
Read MoreThe relative density of gold is very large. in the process of flotation, the gold particles are easy to fall off from the bubble surface after contact with the bubbles.
Read MoreIn oxidized ores, the surface of gold particles is often contaminated or covered by iron oxides.
Read MoreGold has flexibility and ductility,in the grinding often showed flake and surface embedded a layer of mineral particles,to make the gold particle surface roughness.
Read MoreIn addition, due to the friction between the solid particlesnbspin the grinding process, especially between the steel balls and the strong grinding effect of gold particles, gold grain surface by iron and other metal contamination. all of these characteristics adversely affect the floatability of gold.
