Sodium Hydrosulfite Production From Zinc Dust Waste

This report provides an extensive cost evaluation of sodium hydrosulfite production from zinc dust waste. The preparation of sodium hydrosulfite is initiated by the chemical reaction between zinc dust and aqueous solution of sulfur dioxide. The reaction results in the production of zinc dithionate which is further reacted with sodium hydroxide and leads to the formation of sodium hydrosulfite or sodium dithionite as the final product and zinc oxide as the byproduct.

Feedstock for Sodium Hydrosulfite

Sodium hydrosulfite is a chemical compound prepared by using sulfur dioxide, and sodium hydroxide, zinc dust or sodium amalgam as its major feedstock. The procurement of sodium hydrosulfite is governed by some factors, including the availability of its raw materials (including zinc metal, for zinc dust along with other raw materials such as sodium chloride for sodium amalgam production etc.), the processing and production cost of sodium hydrosulfite, along with the variations in its market prices, etc. Additionally, other prominent factors such as the demand for sodium hydrosulfite in different market sectors (including textile, food, paper, and pulp industries), the stability in its supply chain, logistics, trade, and transportation activities, the socioeconomic condition, and governmental policies significantly influences its procurement in the global market.
