Description
Technical field
The invention belongs to mineral floatation technique technical field, it is related to recycling gold, copper and solidification processing in a kind of flotation tailing
Method.
Background technology
Tailing is tcrude ore remaining slag after extraction in mining process, usual stacking processing, still, due to
Contained heavy metal such as lead, zinc, nickel, cadmium, chromium, mercury, arsenic etc. in slag, slag easily make heavy metal-polluted soil nearby during stacking
Content is exceeded, the phenomenon that a large amount of plant deaths occurs, and in slag stacking process in dust undiscipline to air, heavy metal therein
Also easily do harm to huamn body.
In addition, valuable metal element grade is low in common tailing, complicated difficult choosing, and it is longer to accumulate the time, mineral surfaces
Extent of peroxidation is higher.If using technologies such as traditional copper sulphate for activation-direct flotation methods, the rate of recovery of Jin Hetong is not high,
It is embodied in：1, flotation speed is slow, and flotation time is long, and the rate of recovery is low；If 2, strength collecting, lead to sludge and easy-floating gangue
Float-amount is big, and flotation operation concentration ratio is low；3, floating agent dosage is larger, and beneficiation reagent cost is higher.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of method that golden copper and solidification processing are recycled in flotation tailing.
The technical solution used in the present invention is：A kind of method that gold, copper and solidification processing are recycled in flotation tailing, specifically
Steps are as follows：
A, by tailing carry out ore grinding to fineness be -200 mesh account for 80% ore pulp, adjust ore pulp mass concentration be 40~
50%；
B, under stiring by the ore pulp of step A, 700~900g inhibitor waterglass, 100~200g is added by tailing per ton
Collecting agent DF-353,70~90g butyl xanthate+diethyldithiocarbamate and 50~70g terpenic oils, concentrate and tail are recycled through conventional flotation
Ore pulp；
C, the Tailings Slurry of step B is routinely concentrated into the thickened pulp of concentration 65~75%, then by being added in thickened pulp per ton
Coagulator is added in the amount of 6~15kg coagulators in thickened pulp, and continues stirring 5~10 minutes, then routinely stores up, i.e.,
Complete the golden copper of recycling and solidification processing.
Butyl xanthate+diethyldithiocarbamate of the step B is butyl xanthate and diethyldithiocarbamate in mass ratio 1:1 mixture.
The coagulator of the step C is grouped as by the group of following masses part：0.5 part of alum, 5.5~14.5 parts of cement.
The beneficial effects of the present invention are：The rate of recovery of gold, copper in tailing is greatly improved in the present invention, reduces medicament
Cost has saved resource.Gold, copper enter in recycling concentrate, can realize gold recovery up to 68%, and copper recovery is up to 80%.Through solidification
The tailings stored up after agent processing, heavy metal are confined by coagulator, are not entered back into soil and water body, and without the dust that is scattered,
No longer undiscipline gets into the air, and after testing, the tailings stored up after solidification is soaked in water 80 years, without any heavy metal into
In the water for entering immersion.Method energy conservation and environmental protection provided by the invention, it is easily operated, so that the environment near ore flotation factory is protected
Shield, application are strong.
