Chemicals for Mining | Avantor

Quality chemicals for all mining workflows

Avantor manufactures laboratory chemicals and has a complete line of acids, solvents, salts and chemical solutions to suit the demanding requirements of any mining laboratory. Anachemia chemicals are consistently rated as the most popular chemical brand sold by Avantor to mining customers.

We also specialize in fire assay chemicals and custom made flux recipes using the highest purity litharge available. Our fluxes have gold levels as low as less than 1 ppb. Anachemia fluxes are recognized globally for their quality and consistency. Our fire assay fluxes come in a variety of package sizes and custom packaging.

Anachemia also has a long history of providing custom chemical solutions for customers around the world. 

Acids & Bases

Used to prepare cole samples to better improve the permeability of the coalbed and reduce the strength of the coal.

Used in metallurgy, ore extraction and purification, treatment of scrap metal and annealing – among other uses.

Hydrochloric acid is used in ore treatment, extraction, separation, purification and water treatment.

Nitric Acid is used in solvents for separating minerals from ore.

Perchloric acid is used to separate substances in ore, like potassium and sodium.

Sodium Hydroxide may also be known as lye or caustic soda and is used in purifying bauxite ore in aluminum metal extraction.

Used to process copper from ore.

Buffers

Used in pH testing and balancing of water used in sample processing.

Used in pH testing and balancing of water used in sample processing.

Used in pH testing and balancing of water used in sample processing.

Dry Chemicals & Salts

Used to dissolve silica in ore samples.

Used in the process of extracting gold and silver from ore.

Absorbs oxides and litharge during assaying.

Anhydrous Borax is used in almost all Fire Assay fluxes. It lowers the fusion temperature and aids in the formulation of slag.

Helps extract metal from coal ash.

DE can be used as an absorbent or in solution filtration.

EDTA is often used to stabilize metal ions during the mineral ore flotation process.

Flour is a commonly used reducing agent in Fire Assay flux. It is used to reduce litharge to molten lead for the collection of precious metal in the sample.

Where appropriate Fluorspar is used in Fire Assay flux to improve fluidity of the slag by suspending any infusible particles.

Used to regulate substances during sample processing.

Small lead pellets with definite amount of silver which may be added to crucible before fusion or tapped into cleaned lead buttons before cupellation.

Used as a laboratory reagent in gold sample processing.

Lead Foil is typically used in both Fire Assay bullion work and cupellation.  For example, to wrap bullion samples, or for additional cupellation purposes.

Litharge is produced from highly refined lead and offers a very low level of precious metal impurities.

Manganese Dioxide is a primary component of dry-cell batteries. It has a number of other metallurgical applications and may be used as an oxidant in organic synthesis.

Potassium Chlorate has many uses in the Mining lab- such as treating hard water and has an ingredient in Potash.

Potassium dichromate is used to measure uranium concentrations in dissolved uranium metal, ore, or yellow cake samples.

Potassium Iodide is used in ioldine isolation, in redox titrations, and as a source of iodide in organic synthesis.

Potassium Nitrate is used as an oxidizing agent during mineral fire assay and refining.

Potassium Permanganate is used in a mining lab to depress arsenopyrite and pyrrhotite from pyrite to recover gold in bulk pyrite samples.

Potassium Persulfate is used as an oxidizing agent in ore sample processing.

Silica flour is added to samples to protect the crucible in the fusion phase of the Fire Assay process. Insufficient silica levels will result in increased and erratic crucible wear.

Silver foil is added to sample/flux mixtures as an inquart agent facilitating the collection gold or silver in fire assay.

Silver nitrate power is added to sample/flux mixtures as an inquart agent facilitating the collection gold or silver in fire assay.

Silver sulfate power is added to sample/flux mixtures as an inquart agent facilitating the collection gold or silver in fire assay.

Soda ash (sodium carbonate) is a basic component found in fire assay flux. In either light or dense format, it reacts with silica based minerals to form fusible sodium silicates.

Sodium borohydride is used as a reducing agent for gold and silver in acidic solutions.

Sodium chloride can be used to manufacture chlorine, sodium hydroxide, and sodium chlorate.

Sodium Cyanide is commonly used to leach gold from ore samples.

Sodium Hydroxide may also be known as lye or caustic soda and is used in purifying bauxite ore in aluminum metal extraction.

Sodium Nitrate is used in the fire assay process especially to oxidize sulphides, arsenides, antimonides, etc.

Sodium Peroxide is used to determine metallic and nonmetallic elements in a sample.

Sodium Sufate in anhydrous form is typically used in laboratory settings for removing traces of water from organic solutions.

Stannous Chloride is commonly used to prevent coal oxidation and to reduce salts in goal and silver samples.

Zinc is used as a collector to separate gold from cyanide solution in an oxide-reduction reaction.
