Description
Technical field
The invention belongs to mineral floating field, and in particular to a kind of to be used for the floating agent containing golden thiocyanation castaway slag.
Background technology
China has just carried out the large scale mining of gold since the seventies in last century and has selected smelting.But by gold smelting at that time
The limitation of industry processing techniques, the recovery process technology of gold are substantially gold containing ore by broken, ball milling, table concentration or added
Cymag carries out the complex compound of reaction generation gold through techniques such as zinc dust precipitations under conditions of lime does protection alkali, is finally melted
Gold is smelt, element sulphur is not almost reclaimed, and the golden rate of recovery is given up only between 65~70% after largely carrying gold containing golden tailings
Abandon and heap is stored in Tailings Dam.These, through analyzing sulfur-bearing, Jin Heyin, cause the wasting of resources and environmental pollution containing golden tailings.Flotation medicine
Agent is the important component of flotation, is to solve mineral difficulty to select problem by improving floating agent and Development of Novel floating agent
One of important means.It is existing it is most widely used containing golden tailings collecting agent have xanthate, black powder, ammonium black powder etc., but these collecting agents
Collecting ability is although good, but its selectivity is all universal relatively low and CN in by slag-Influence, Floatation Concentrate Grade is low, flotation into
This height, resource cannot be reclaimed fully, cause the wasting of resources.
The content of the invention
Contain the shortcomings that golden tailings flotation recovery rate is low, concentrate grade is low present invention aim to address existing, there is provided one
Kind improves the floating agent containing golden tailings flotation recovery rate, concentrate grade.
To achieve the above object, the technical solution adopted by the present invention is, a kind of to be used for the flotation containing golden thiocyanation castaway slag
Medicament, by weight, including following component:200~320 parts of calgon, 1500 ~ 2500 parts of sodium metasilicate, ethyl ammonia sulfate(Z-
200)40 ~ 60 parts, 30~55 parts of copper sulphate, 66 ~ 110 parts of butyl xanthate, 133 ~ 220 parts of isoamyl xanthate, 2# oil(Terpenic oil)
50~110 parts.
Preferably, it is described to be used for the floating agent containing golden thiocyanation castaway slag, by weight, including following component:Six
250 parts of sodium metaphosphate, 2000 parts of sodium metasilicate, 50 parts of ethyl ammonia sulfate, 40 parts of copper sulphate, 90 parts of butyl xanthate, isoamyl xanthate 180
Part, 80 parts of 2# oil.
The butyl xanthate is sodium n-butyl xanthate, and the isoamyl xanthate is isopentyl sodium xanthate.
The beneficial effect comprise that:Gangue is suppressed using calgon, waterglass suppresses iron mineral, second sulphur ammonia
Ester Z-200 makees the collecting agent of copper sulfide, and copper sulphate makees activator, and butyl xanthate, isoamyl xanthate make collecting agent, and 2# oil bubbles
Agent;Greatly improved using the concentrate grade powder after the floating agent floating and enriching of the present invention, the tenor of flotation dreg is low, recovery
Rate is up to 80%, and concentrate Gold grade is improved to 20g/t after enrichment, and silver-colored grade, which is improved to 220g/t, sulfur content, reaches 33%.Flotation
Cost declines to a great extent, and has effectively reclaimed resource, protects environment.
