Nitric Acid 55-60%

Gandi Chemical Solutions supplies Nitric Acid 55-60% (CAS 7697-37-2) to mines, concentrators and mineral processing plants. It is supplied as technical grade. Packaging: 34kg, 273kg, 1350kg (drum cost refundable). Priced by quotation, with a current safety data sheet on every consignment.

Nitric acid in the 55 to 60 percent range is a strong, oxidizing mineral acid used in metal etching, fertilizer intermediates, and various ore leaching and digestion processes. It appears as a transparent liquid that can take on a yellowish tint as it ages or is exposed to light, a sign of dissolved nitrogen oxides. The acid is aggressively corrosive to metals and tissue alike, and its fumes irritate the respiratory tract, so it calls for acid-resistant storage and PPE at every handling step. GCS ships it in 34kg, 273kg, and 1350kg drums with the container deposit refunded on return.

Where nitric acid 55-60% is used

• Passivation and pickling of stainless steel
• Fertiliser and nitrate salt manufacture

Specification and grade

Technical-grade nitric acid at 55–60%, CAS 7697-37-2, a transparent colourless to yellowish corrosive liquid. The yellow deepens with age and warmth as dissolved nitrogen dioxide forms; this is normal for stored nitric acid and is not itself a rejection criterion.

Handling and storage

A strong oxidiser as well as a strong acid — H272 may intensify fire, H290 may corrode metals, H314 severe skin burns and eye damage, and it is corrosive to the respiratory tract. Segregate it from organics, solvents, sawdust and combustible packaging: a spill onto pallet wood is a fire, not just a clean-up. Store cool and shaded in dedicated bunding. Nitric acid is one of the few acids where 304/316 stainless performs well; avoid copper, brass and most elastomers.

Packaging and supply

Supplied in 34kg, 273kg and 1350kg containers with a refundable drum deposit. Because of the oxidiser classification, confirm your storage segregation before the first delivery — we would rather resolve that at quotation stage than at your gate.
