Product detail description

Nitric Acid is used as is in the digestion of wirewool where silver is NOT to be recovered together with gold since it dissolves most metals but gold. It is a colourless highly corrosive mineral acid. Older samples however acquire a yellow cast due to decomposition into oxides of nitrogen.

Nitric Acid 65% (hg 69.5% , Nitric Acid Fuming 100%, Nitric Acid Solution, CLP AA/ICP Nitric Acid, Nitric Acid 1.42 - TECHNIQUE, Contract Lab Program AA/ICP Nitric Acid, Nitric Acid 1.42 - ANALYPUR Nitric Acid 70%, Nitrate Acid

Nitric Acid is a colourless highly corrosive mineral acid. Older samples however acquire a yellow cast due to decomposition into oxides of nitrogen.

Most commercially available Nitric Acid has a concentration of 68%.

5. NITRIC ACID USE IN MINING:

Nitric Acid is used as is in the digestion of wirewool where silver is NOT to be recovered together with gold since it dissolves most metals but gold. It dissolves the wirewool and many other metals through the following reaction.

2HNO3(aq) + M(metal) → H2(g) + 2MNO3(aq) / M(NO3)2

In acid digestion, nitric acid also helps deal with copper impurities in bullion which at low cyanide concentrations also tend to react with cyanide and thus cannot be separated before this stage.

Acid washing of Carbon: HNO3 is also used in the acid washing of activated carbon for chemical regeneration. Here the acid reacts with alkaline precipitates that coat and clog the carbon surface and micro-pores thus restoring its activity. A 5% solution is used for this application.

Other uses of Nitric Acid include:

  • Production of fertilizers. Over 70% of the global nitric acid output is used to make ammonium nitrate
  • Production of explosives for use in the mining and construction industries
  • Rocket propellant

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.

4.Environmental impact

 

-       Acetic acid biodegrades readily under both aerobic and anaerobic conditions.

 -        Acetic acid does not absorb light with wavelengths >290 nm(4), and is not expected to be susceptible to direct photolysis by sunlight(SRC).

-        Incase of spillage neutralize spill with soda ash or lime.
