Abstract
The invention discloses a kind of cathode carbon pieces flotation recovery processing flotation agent, are formulated by following raw material: water, kerosene, 2# medicament, waterglass.Flotation agent of the invention, using kerosene as agent for capturing, waterglass as inhibitor, 2# medicament as activator complexing agent etc., be easy to disperse in water phase, the charcoal purity that flotation obtains rises to 96.8% or more, improves flotation effect.
Description
Technical field
The present invention relates to a kind of cathode carbon pieces flotation recovery processing flotation agent, belong to waste cathode carbon block recovery technology neck
Domain.
Background technique
During Aluminum Electrolysis Production, every 3-6 is replaced or is overhauled to electrolytic cell, and electrolytic cell replacement or maintenance generate
A large amount of solid waste, the waste material are either stacked or are filled, and all can bring pollution to surrounding air, water source, soil, simultaneously
Also result in the waste of resource.According to statistics, during Aluminum Electrolysis Production, 10,000 tons of aluminium of every production, electrolytic cell replacement or maintenance are generated
Solid waste in about 100 tons of waste and old cathode carbon block or so, the annual electrolytic aluminium in China production generate waste and old cathode carbon block amount
About 25 tons or more.
It is detected according to " hazardous waste judging standard leaching characteristic identification " (GB 5085.3-2007), cathode carbon pieces master
Charcoal in ingredient is wanted to account for 50% or so, fluoride salt accounts for 30%(, and wherein soluble fluoride accounts for 25%, soluble hydrogenation object 0.02%).Cathode
It is poisonous and harmful that hydrolysis generation hydrogen fluoride, hydrogen cyanide, ammonia etc. can occur for carbon block chance water, and the liquid reacted is then highly basic
The toxic liquids such as property fluorochemical, hydride.
Currently, Some Enterprises recycle above-mentioned waste and old cathode carbon block, and alkali leaching method for floating is one such time
Receiving method leaches waste and old cathode with NaOH solution under heating stirring adjusting, leached mud is handled using floatation
To purity be 95% or more charcoal and purity be 95% electrolyte, leachate is reacted with hydrochloric acid obtains purer ice crystal, and soaks
Out waste liquid and repeatedly the flotation waste water bleaching powder processing after circulation decompose and cyanide and recycle calcirm-fluoride.Flotation agent used in it
Generally diesel oil, turpentine oil, sodium metasilicate etc. cooperate, which need to assist magnetic separation, and flotation effect has to be hoisted.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of processing of cathode carbon pieces flotation recovery
With flotation agent, to improve flotation effect.
To achieve the above object, the technical solution adopted by the present invention is that: flotation is used in a kind of processing of cathode carbon pieces flotation recovery
Agent, which is characterized in that be formulated by following raw material: water, kerosene, 2# medicament, waterglass.
Preferably, in above-mentioned cathode carbon pieces flotation recovery processing flotation agent each raw material amount ratio, by weight for,
Water: kerosene: 2# medicament: waterglass=3:1:2:1-2.
Preferably, above-mentioned 2# medicament is mixed by the raw material of following weight percent: methylene chloride 40-60%, rosin
Alcohol 30-40%, sodium lignin sulfonate 10-20%, graphene 5-8%.
Compared with prior art, the beneficial effect that the present invention has is: flotation agent of the invention, using kerosene as capture
Agent, waterglass, as activator complexing agent etc., are easy to disperse in water phase, the charcoal that flotation obtains is pure as inhibitor, 2# medicament
Degree rises to 96.8% or more, improves flotation effect.
Specific embodiment
Presently in connection with specific embodiment, next the invention will be further elaborated.

The present embodiment cathode carbon pieces flotation recovery processing use flotation agent, be formulated by following raw material: water, kerosene, 2# medicament,
Waterglass, and water: kerosene: 2# medicament: waterglass=3:1:2:1.
Above-mentioned 2# medicament is mixed by the raw material of following weight percent: methylene chloride 50%, abienol 30%, wooden
Plain sodium sulfonate 12%, graphene 8%.
Embodiment two
The present embodiment cathode carbon pieces flotation recovery processing use flotation agent, be formulated by following raw material: water, kerosene, 2# medicament,
Waterglass, and water: kerosene: 2# medicament: waterglass=3:1:2:2.
Above-mentioned 2# medicament is mixed by the raw material of following weight percent: methylene chloride 40%, abienol 40%, wooden
Plain sodium sulfonate 15%, graphene 5%.
