Environmental applications Nahs is an effective tool in a waste treatment programs requiring stabilization and reduction of heavy and toxic metals through precipitation. Mining Nahs is an effective means of sulfidizing oxide ores and is used most commonly to separate copper (cu) from molybdenum (mo). Nahs does this by depressing the cu from the cu-mo concentrate, allowing for conventional floatation metal separation. Pulp and paper Nahs is used in the kraft pulping process to prepare synthetic cooking liquor (white liquor) during pulp mill outages and as a Make-up chemical to replace lost sulfur values. It may also be used as a scrubbing media forresidual chlorine dioxide generated and consumed in mill bleach plants. Tanning Nahs is used for removing hair from hides at the beginning of the tannery process. Packing: 25kgs or 900 kgs PP and PE bag; 150kgs new iron drum |
