Nitric Acid 68% – Oxidizer & Passivation Specialist
High-Purity Low-NOx Formula for Refractory Gold Ore, Stainless Passivation & PCB Synthesis
1 The Product Narrative
In the gold processing circuits of West Africa, Nitric Acid 68% is indispensable for breaking down sulphide matrices in refractory ores, unlocking captured gold values before cyanidation.
For the broader manufacturing sector, this grade serves as the gold standard for stainless steel passivation—creating a uniform chromium-oxide layer that prevents corrosion in food-grade equipment and offshore structures.
Its oxidizing strength also makes it a primary agent in industrial etching and chemical synthesis.
Low-NOx Stabilization: 20% Longer Bath Life
Our proprietary low-NOx stabilization process prevents premature yellowing and degradation, extending bath life by 20% compared to standard commodity grades. For passivation lines, this translates to fewer bath dumps, reduced waste treatment costs, and a 12% reduction in acid consumption per square meter of treated metal.
