cobaltspar - Preparation Method
Open Data Verified Data
hydrochloric acid method: after metal cobalt or cobalt-containing waste material reacts with hydrochloric acid to generate a cobalt chloride solution, sodium carbonate is added to react to generate a cobalt carbonate precipitate, which is rinsed, centrifuged and dried to obtain a cobalt carbonate finished product.

cobaltspar - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| cobalt mineral additive | cobalt exists in various organs, and is abundant in liver, kidney, adrenal gland, spleen, pancreas and stomach tissues. vitamin B12 contains 4.5% cobalt. Cobalt has the effect of activating arginase, inhibiting the activity of cytochrome oxidase, etc., is related to the metabolism of carbohydrates and proteins, and participates in the synthesis of vitamin A, vitamin B, vitamin C, and vitamin D. Cobalt deficiency is manifested as digestive disorders, growth stagnation, mental weakness, anemia and weight loss, and sows have miscarriage. The amount of cobalt required per 1000g of dry feed is 0.5~2 mg for pregnant and lactating sows and 0.5~1 mg for other pigs. Cobalt supplements include cobalt sulfate, cobalt carbonate, cobalt chloride, etc. |
| toxicity | inhalation of cobalt compounds sometimes leads to bronchial asthma; grinding cobalt compounds can cause acute dermatitis and sometimes ulcers on the skin surface. The maximum allowable concentration of metal cobalt and cobalt oxide is 0.5 mg/m3. Antivirus masks should be worn at work to prevent aerosol from damaging respiratory organs; dust-proof overalls and protective gloves should also be worn at work to protect the skin. Attention should be paid to dust prevention and dust removal. |
| Use | Used as concentrator, catalyst, pigment for camouflage paint, feed, micro-fertilizer, ceramic and raw material for producing cobalt oxide Used to make cobalt oxide, It is the raw material for manufacturing lithium battery cathode materials. It is the raw material for the production of other cobalt salts and cobalt oxides in chemical production. The ceramic industry is used as a colorant. Used as a mineral agent in the mining industry. The organic industry is used to make catalysts, camouflage coatings and chemical temperature indicators. Used as trace element fertilizer in agriculture. Used as an analytical reagent in analytical chemistry. Used as concentrator, catalyst, pigment for camouflage paint, feed, trace fertilizer, ceramics and raw material for producing cobalt oxide Used as a general reagent, also used for cobalt salt manufacturing and porcelain coloring Used for cobalt salt manufacturing and glass and porcelain coloring |
| production method | hydrochloric acid method cobalt metal or cobalt-containing waste reacts with hydrochloric acid to generate cobalt chloride solution, then sodium carbonate is added to react to generate cobalt carbonate precipitate, which is rinsed, centrifuged and dried to obtain cobalt carbonate finished product. Its Co 2HCl → CoCl2 H2 ↑ CoCl2 Na2CO3 → CO3 ↓ 2NaCl |
