Antiscalents are used for the control of scale build-up in pipes and equipment. Products are specially formulated to suit each customer's needs and requirements.
Josblue is an effective acidic liquid detergent specifically formulated to remove scale build-up and to clean heat exchangers.
Flushing heat exchangers regularly with JosBlue will greatly increase the intervals at which the heat exchanger plate packs need to be removed for chemical cleaning. Depending on the amount of scale-forming material in the elution fluid it may be necessary to flush the heat exchangers after each strip.
JosBlue is available in 25 litre, 200 litre and 1000 litre containers.
Gold Leach Accelerants
LeachAid™ UL is a proprietary blend manufactured by LogiChem and sold worldwide by ConSep Pty Ltd. It is a dry product most commonly packed in easy-to-handle containers and is also available in bulk packaging.
The primary use for LeachAid™ is as a gold leach enhancer. LeachAid™ is used very effectively in intensive cyanidation reactors such as the Acacia Reactor built and installed by ConSep Pty Ltd.
LeachAid is a proprietary blend product manufactured by LogiChem. The LeachAid™ XL is only available in Australia.
The primary use for LeachAid™ is as a gold leach enhancer. LeachAid™ is used very effectively in intensive cyanidation reactors such as the Acacia Reactor built and installed by ConSep. The XL refers to the addition of lead nitrate which further aids the leaching of some concentrates.
Lead Nitrate is used to enhance gold recovery. The potential benefits of lead nitrate addition prior to or during pre-oxidation include:
- Lead ions may activate passivated gold surfaces by reacting with sulphide species on gold surface.
- Lead can be precipitated on the gold via under-potential deposition, accelerating gold dissolution.
- Lead may depolarize the gold surface and prevent passivation.
- Lead binds with sulphide ions and removes it from solution by forming insoluble PbS.
- It also catalyses sulphide oxidation to sulphate.
As a result, the dosing of lead nitrate to sulphide ores in concentrations that typically range between 50 to 100 grams per tonne of milled ore is likely to enhance the gold recovery rates and reduce the consumption of sodium cyanide.
Xanthates are used as flotation agents in mineral processing because they selectively link metal ore particles to air bubbles, this gives the precious metal, such as gold, buoyancy over the less valuable iron ore. The result allows the metal to be easily removed for further processing.
Xanthates are produced by the reaction of an alcohol with sodium or potassium hydroxide and carbon disulfide. The major xanthates produced worldwide include:
- Sodium ethyl xanthate (SEX)
- Sodium isopropyl xanthate (SIPX)
- Sodium isobutyl xanthate (SIBX)
- Potassium amyl xanthate (PAX)
LogiChem supplies xanthate in both solution and dry form.
Copper sulphate (CuSO4.5H2O) has many applications across a wide variety of industries, in the mining industry it is generally used as an activator in the froth flotation of lead, zinc, cobalt and gold ores.
LogiChem supplies copper sulphate in both solution and powder form.
Sodium Hydrosulphide (NaHS)
Sodium hydrosulphide (NaHS) is used in copper mining as a flotation agent which separates impurities.
LogiChem supplies sodium hydrosulphide in both solution and dry form.
Various Process Chemicals
Sodium hydroxide (NaOH), also known as lye and caustic soda, is a caustic metallic base. It is used as an alkalising agent. Specifically in the gold mining industry it is used as a pH adjuster, and in carbon stripping.
Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution.
Iron (III) Sulphate (Fe2(SO4)3) or Ferric Sulphate has a variety of applications in water treatment. It can be used to neutralise alkaline water because it increases coagulation in water treatment and produces a large shift in pH.
LogiChem supplies ferric sulphate in both solution and dry form.
Sodium carbonate (also known as washing soda, soda crystals or soda ash or "Soda Carbonate"), Na2CO3, is a sodium salt of carbonic acid.
Soda Ash can be used as a mild alkalising agent.
LogiChem supplies soda ash in both solution and dry form.
Citric acid is used in chemical cleaning and metal passivation.
LogiChem supplies citric acid in both solution and dry form.
Smelting Flux Reagents
Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate.
Borax has a wide variety of uses. In the mining industry it is used as a flux reagent in gold and silver smelting. In small scale mining operations it is used to replace mercury in the extraction of gold.
LogiChem supplies borax in powder packed in 25kg bags.
Fluorite (also called fluorspar) is a halide mineral composed of calcium fluoride, CaF2.
Fluorspar is used as a flux reagent.
LogiChem supplies fluorspar in 25kg bags.
Products are specially formulated to suit each customer's needs and requirements and available in a variety of sizes and containers.
