Abstract
The invention discloses a resourceful recovery process for a waste lithium ion battery. The process comprises the following steps: putting a waste battery into brine for discharging, draining off moisture, then crushing the waste battery, oxidizing the crushed waste battery in a rotary kiln with a temperature of 800 DEG C, taking the oxidized waste battery out from the rotary kiln after oxidation combustion for 40 min, adding ammonium sulfate according to certain proportion and carrying out roasting at a temperature of 400 DEG C so as to allow elemental cobalt to be precipitated in the form of sulfate, wherein a ratio of the raw material to ammonium sulfate is 1: 2.5; and carrying out dissolving with hydrochloric acid and filtering, pumping a filtrate into a P507 extraction system consisting of hydrochloric acid, kerosene and phosphate ester for fractional extraction, separating elemental cobalt in the waste lithium ion battery by adjusting the concentration of hydrochloric acid, adding ammonium bicarbonate and carrying out deposition, filtering and burning so as to prepare cobalt oxide.
Description
Technical field
The invention belongs to utilization of waste as resource technical field, more specifically say a kind of discarded lithium ion battery resource recovery technology.
Background technology
Development along with the communication technology and electronic technology, production and the consumption of lithium ion battery increase sharply, thereby produced a large amount of discarded lithium ion batteries, the lithium ion battery that the LiCoO2 of take is positive electrode contains the materials such as cobalt acid cobalt, hexafluorophosphoric acid cobalt, organic carbonate, polyethylene, carbon materials, Copper Foil and aluminium foil, generally contain the metals such as more cobalt, cobalt, copper, nickel, there is the value of recycling.And the general link of separating out reclaiming adopts hydrochloric acid to separate out more, when the metallic elements such as cobalt, cobalt leach, HCl corrosivity is strong, volatile, also will produce chlorine, need in airtight container, carry out.
Summary of the invention
The object of the invention is to overcome the defect of prior art, the technical method of the discarded lithium ion battery of a kind of new recovery is provided, utilize this technical method not only the metallic cobalt element in discarded lithium ion battery can be separated separately, also have extract efficient, fast, completely and save time, the advantage such as solvent and energy consumption.
The present invention is achieved by the following technical solutions: put waste battery into salt discharge in water, drain away the water, pulverize, in rotary kiln, be oxidized, 800 ℃ of furnace temperature, oxidizing fire is come out of the stove for 40 minutes, add according to a certain percentage ammonium sulfate roasting, sintering temperature is 400 ℃, and raw material and ammonium sulfate ratio are 1 ︰ 2.5, and metallic cobalt element is separated out with the form of sulfate.Then use dissolving with hydrochloric acid, filtration, the P507 extraction system that filtrate is pumped into hydrochloric acid, kerosene, phosphate composition is carried out fractional extraction, by regulating concentration of hydrochloric acid, makes metallic cobalt element separated, adds ammonium bicarbonate precipitation, filtration, calcination, makes cobalt oxide.
Embodiment
1, raw material.Waste battery is put in the nacl aqueous solution and soaked electric discharge, drain away the water, pulverize.
2, oxidation.The raw material crushing combustion oxidation in rotary kiln, 800 ℃ of furnace temperature, oxidizing fire is come out of the stove for 40 minutes, and various organic compound combustions are rejected completely, and various metallic elements are also oxidized as much as possible simultaneously.
3, ammonia soaks.To add according to a certain percentage ammonium sulfate roasting through snperoxiaized raw material, sintering temperature is 400 ℃, and raw material and ammonium sulfate ratio are 1 ︰ 2.5, and metallic cobalt element is separated out with the form of sulfate.
4, acid is molten.Raw material dissolving with hydrochloric acid by soaking through ammonia, makes not have oxidized metallic cobalt element to enter solution, filters, and removes sediment.
5, extraction.The P507 extraction system that filtrate is pumped into hydrochloric acid, kerosene, phosphate composition is carried out fractional extraction, by regulating concentration of hydrochloric acid, makes metallic cobalt element separated.
6, alkali is heavy.In raffinate, add ammonium bicarbonate precipitation, filtration, obtain Cobalt carbonate sediment.
7, calcination.Cobalt carbonate is sent into rotary kiln and carry out calcination, make cobalt oxide.
