SECTION 4: PRODUCTION METHODS

Method 1: Metallic Nickel Method

Process:

1. Water is added to the reactor, then sulfuric acid is added to form 30°Bé solution

2. Metallic nickel is added, and nitric acid is added in fractions

3. Reaction is carried out until concentration reaches 48-50°Bé

4. Crystallization and filtration are performed

5. Crude crystals are washed with water

6. Water is added to dissolve to 30°Bé

7. Barium carbonate is added to neutralize free acid

8. Hydrogen peroxide is added to oxidize divalent iron and hydrolyze it

9. Purified solution is clarified

10. Small amount of sulfuric acid is added to adjust pH to 3-4

11. Concentration, crystallization and centrifugal dehydration are performed

12. Nickel sulfate product is obtained

Method 2: Recovery Method

Process:

• Electrolytic waste liquid from copper smelting process is purified

• Crystallization and dehydration are performed

• Nickel sulfate is obtained

Method 3: From Cobalt-Producing Nickel-Containing Waste Liquid

Process:

1. Nickel carbonate is precipitated from spent nickel sulfate solution using soda ash solution

2. Nickel carbonate is dissolved in sulfuric acid

3. Nickel sulfate is prepared

SECTION 20: CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Carcinogenic (H350). Nickel compounds are known human carcinogens (IARC Group 1).

• May cause genetic defects (H341). Handle with extreme care.

• May damage the unborn child (H360D). Use extreme caution.

• May cause allergic skin reaction (H317) and respiratory sensitization (H334). Use proper PPE.

• Harmful if swallowed or inhaled (H302/H332). Use adequate ventilation and PPE.

• Very toxic to aquatic life with long-lasting effects (H410). Prevent environmental release.

• Nickel salts can damage human skin and disrupt cellular metabolism.

• Maximum allowable concentration: Divalent and trivalent nickel oxides/sulfides: 0.5 mg/m³ (as Ni); Nickel salts in water aerosol: 0.0005 mg/m³ (as Ni).

• Incompatibilities: Keep away from strong oxidizing agents, strong reducing agents, aluminum, magnesium, zinc, sodium, and potassium.

BEST PRACTICE RECOMMENDATIONS:

• Electroplating Industry: Use as primary nickel source for nickel plating and electroless plating; maintain proper bath concentrations; ensure proper waste treatment and recycling.

• Battery Industry: Use battery grade nickel sulfate (Ni ≥ 22.2%, Co ≤ 0.4%) for ternary precursor production; maintain strict purity specifications for high-performance batteries.

• Catalyst Applications: Use as catalyst for hydrogenation and oxidation reactions; handle under controlled conditions.

• Handling: Use in well-ventilated areas or under fume hood; wear chemical-resistant gloves (neoprene, nitrile), safety goggles, face shield, and appropriate respiratory protection; avoid creating dust.

• Personal Protective Equipment: Use impervious gloves, chemical safety goggles, full face shield, protective clothing, and NIOSH-approved respiratory protection.

• Hygiene: Do not eat, drink, or smoke while handling; wash hands thoroughly after handling; shower at end of work shift.

• Storage: Store in tightly closed, properly labeled containers in dry, well-ventilated conditions; keep away from heat, moisture, and incompatible materials; do not store under active chlorine and hot sun.

• Spill Response: Avoid creating dust; wear full PPE; vacuum or wet sweep; place in sealed containers for disposal; prevent discharge to water bodies.

• Disposal: Dispose of in accordance with local, regional, and national regulations; do not discharge into drains or water bodies; nickel compounds are regulated as hazardous waste.
