To prepare high-purity cobalt sulfate, first prepare pure cobalt sulfate solution, then evaporate and crystallize through MVR and dry at low temperature to obtain high-purity cobalt sulfate product. The product is mainly used as cathode material of lithium ion battery; Used for electroplating, alkaline batteries, pigments, catalysts, analytical reagents, additives, adhesives, etc.
2. Preparation technology of high purity cobalt chloride
High purity cobalt chloride products refer to cobalt chloride crystals with cobalt content ≥ 24.28%. Executive standard: Q / gzty0 Dongrui Food Group Co.Ltd(001201) 8, which is higher than the national standard for refined cobalt chloride GB / t265252011 and meets the requirements of battery grade cobalt chloride. To prepare high-purity cobalt chloride, first prepare pure cobalt chloride solution, then evaporate and crystallize through MVR and dry at low temperature to obtain high-purity cobalt chloride product. The product is a famous brand product in Jiangxi Province, which is mainly used in the cathode material of lithium cobalt oxide battery; It is also used in analytical reagents, humidity and moisture indicators, ammonia absorbers, etc. 3. Preparation technology of battery grade cobalt trioxide
Battery grade Co3O4 products refer to Co3O4 powder with cobalt content ≥ 72.8%. Executive standard: Q / gzty Chang Jiang Shipping Group Phoenix Co.Ltd(000520) 18, which is higher than non-ferrous industry standard YS / T 6332007 and meets the requirements of battery grade Co3O4. To prepare battery grade Co3O4, first prepare pure cobalt chloride solution, and then continuously add the prepared cobalt chloride solution and sodium hydroxide solution into the reactor in proportion to accurately control the formation and growth rate of hydroxyl cobalt crystal nucleus, so as to obtain battery grade Co3O4 products. The product is mainly used as cathode material of lithium cobalt oxide battery.
4. Deep purification technology of cobalt solution
In the process of solvent extraction, the organic phase in the aqueous phase generally exists in the form of suspended state, dispersed state, emulsified state and dissolved state. The particle size of suspended beads is generally greater than 100 um, which is easy to float on the liquid surface to form oil film or oil layer, which is easy to separate and recover; The particle size of dispersed beads is generally 10 - 100 um. They are suspended in the solution with tiny oil beads and are unstable. After standing for a certain time, they often form oil slick; The particle size of emulsified beads is less than 10um, generally 0.1 - 0.2um; The particle size of dissolved beads is generally smaller than that of emulsified beads, and some can be as small as several nanometers, which are dissolved in the aqueous phase.
The technology is independently invented by the company in combination with the actual production. Its characteristics are: the oil removal treatment of cobalt product liquid is carried out with renewable adsorbent, which mainly uses the structural characteristics of the adsorbent with large pores, and the organic matter is macromolecular matter, which can enter the pores of the adsorbent; The saturated adsorbent can be regenerated and recycled through the heating equipment independently developed by the company, and the organic matter can be volatilized and degraded. The adsorbent is used for deep oil removal of cobalt solution, so that the oil content of cobalt solution is reduced from 15mg / L to about 1mg / L. The technology simplifies the solution purification process, improves the product quality, recycles the adsorbent, reduces the production cost and cobalt loss rate, and realizes the goal of cleaner production.
