Description
Technical field
It the present invention relates to a kind of heating vulcanizing equipment of lead-zinc, is set to the pretreatment before lead-zinc oxide ore flotation
It is standby.Vulcanizing treatment is heated suitable for lead-zinc；The heating vulcanizing treatment of cupric oxide ore；At the heating vulcanization of zinc smoke
Reason.Vulcanizing treatment is heated before being especially adapted for use in the oxidation nonferrous metals ore flotation in high altitudes and cold area.
Background technique
Xanthate floatation is used after the vulcanization used when prior art flotation lead oxide mineral.Vulcanization-xanthate method mechanism is
Surface sulfide is carried out to lead oxide in advance, so that lead oxide surface is covered one layer of hydrophobic stronger sulfide film, then with xanthate class
Collecting agent carries out flotation.Usually used vulcanizing agent is vulcanized sodium.But it is noted that process conditions, vulcanized sodium cannot mistakes when vulcanizing
Amount, because excessive vulcanized sodium can make sulphur hydrogen ion (HS) and sulphion (S) excessive concentration in ore pulp, can inhibit to vulcanizate
Lead oxide mineral swim.A large amount of vulcanized sodium makes the pH value of ore pulp be more than ± 0.5, over cure and undervulcanization in flotation, portion
Divide lead oxide that can all be lost in tailing, causes the flotation recovery rate of lead relatively low.Most handy low speed non-aerating stirring when vulcanization, with
It reduces the oxidation of vulcanized sodium and avoids the pH value of peeling, the flotation of ore particle surface sulfide film that from should being maintained at 8.5-11.Vulcanizing agent with
The dosage of collecting agent xanthate is higher, needs to add the inhibitor of the gangues such as waterglass and calgon, the bad control of floatation process
System, lead foam are easy to emit slot, and production cost is higher, and the high lead oxide of iron content can not flotation.
The zinc oxide ore flotation of the prior art, with xanthate floatation after the heating vulcanization being industrially able to use at present.
Vulcanization-xanthate method mechanism is to carry out surface sulfide to zinc oxide in advance, and zinc oxide surface is made to cover one layer of hydrophobic stronger sulphur
Compound film, then flotation is carried out with xanthate collectors.Early stage when slurry temperature is heated up to 50~60 DEG C the study found that have
Conducive to the vulcanization of Zinc oxide minerals and the absorption of medicament, but vulcanizing agent can excessively inhibit the effect of xanthate and mineral surfaces, and oxygen
After changing zinc mineral vulcanization need that xanthate collecting could be used after adding copper sulphate for activation.Vulcanization-xanthate method is first sloughed less than 0.001mm
Thin mud, after concentration, then by warming up pulp to 50-70 DEG C, then use vulcanized sodium sulfidation-oxidation zinc ore, and add copper sulphate for activation
Sulfureted zinc oxide ore, finally makees main collecting agent with long-chain xanthate, and diesel oil, tar etc. make supplementary catching agent, terpenic oil
Make foaming agent, waterglass makees gangue inhibitor, Flotation of Zinc Oxide mineral.What although the method for heating Flotation of Zinc Oxide mine had can obtain
To preferable technic index but in process of production, usually fluctuated because various factors control is improper, if raw ore is containing a large amount of
Effect is less good when iron hydroxide.Floatation process is more difficult to control, and the high zinc oxide flotation recovery rate of iron content is low.Using coal-fired or combustion
Gas boiler and resistance wire heat ore pulp indirectly, and warming up pulp total amount is high, and rate of warming is slow, and the thermal efficiency is low, heat at high cost.Sulphur
Agent oxidation loss is high, and vulcanizing agent and activator copper sulphate and the dosage of collecting agent xanthate are higher, and heating is at high cost, and equipment can not
Enlargement and automation.
Summary of the invention
In order to overcome lead-zinc to be in the prior art unable to accurately control the additive amount of vulcanizing agent, oxygen in floatation process
Change zinc surface and cover one layer of hydrophobic stronger sulfide film built on the sand, floating operation technique is cumbersome, and warming up pulp total amount is high, adds
Warm speed is slow, and the thermal efficiency is low, heats at high cost.Vulcanizing agent oxidation loss is high, and vulcanizing agent and activator copper sulphate and collecting agent are yellow
The defects of dosage of medicine is higher, and heating is at high cost, and equipment can not be enlarged and be automated.The present invention provides a kind of using density biography
