Product detail description
Sodium Cyanide (NaCN) 98%: Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore.

Sodium cyanide cost contributes an estimated 5% towards cash costs for most mining companies, and it is tied to long-term profitability. As a result, a reliable, low-cost sodium cyanide supply partner is an important part of any gold mining company.

Proven Knowledge and Experience
We are committed to efficiency & safety, and we have been exporting sodium cyanide for the past 10 years. Our export market is mostly in Africa with majors customers in Zimbabwe, Tanzania, Sudan, South Africa, Ghana, and other resource-rich countries.

Sodium Cyanide Import procedures
As a Sodium Cyanide supplier, we assist our clients to comply with export laws from South Africa.

Our End Users and importers are required to provide their "Import permit license" and "End-user Certificate" declaring the specific application. Depending on the jurisdiction the "Import permit license" is usually issued by the ministry of mines, while the miner or importer must provide the “End-user Certificate”.

The licensing process requires 30 days before we can commence the first shipments.

Product application
Synonyms: Glacial acetic acid; Acetic acid solution; acetic acid 50%; acetic acid, of a concentration of more than 10 per cent, by weight, of acetic acid; Acetic Acid Glacial BP; Natural Acetic Acid; Acetic acid (36%); Acetic acid, food grade; Acetic Acid Glacial; GAA; Acetic Acid, Glacial
It is a colourless liquid that when undiluted is also called glacial acetic acid. It has a distinctive sour taste and pungent smell.

Acetic acid uses: Additive in industrial explosives in Mining.
Other uses include use of acetic acid in the production of vinyl acetate monomer, acetic anhydride and ester production.

Chemical gassing agents -In the case of emulsion explosives, using Acetic acid can accelerate the gassing process. The chemically gassed emulsions may take 40 50 minutes for completion of gassing within the blast holes, particularly when the emulsion is colder.

In cases where acetic acid is used, it is added to the emulsion prior to gassing, the desired amount of acid is mixed in the emulsion, before adding the gasser.

A gassing solution comprising sodium nitrite in water together with the selected enol compound and acetic acid is introduced into the emulsion explosive at the blast hole by entraining the gassing solution into a stream of the emulsion explosive using pumps.

The solution pH is an important parameter in the gassing of emulsion explosives due to the high cost associated with acid addition therefore a pH value should preferably be maintained at 4.1 or below.
