Where mining chemicals go to work

Reagent choice is decided by the ore, not by the price list. A collector that recovers well on one orebody underperforms on the next, so most operations arrive at their suite through plant trials. This range covers the reagents themselves and the bulk acids, alkalis, solvents and treatment chemicals a plant orders alongside them.

  • Sulphide flotation

    Xanthates and dithiophosphates make sulphide surfaces water-repellent so they attach to air bubbles. Dosage is measured in grams per tonne, so a small change in reagent quality shows up directly in recovery.

  • Gold leaching

    Sodium cyanide dissolves gold from milled ore in an alkaline slurry. Lime holds the pH high enough to keep hydrogen cyanide from forming, which makes the two an order pair rather than two separate lines.

  • Acid leaching and pH control

    Sulphuric acid at strength does the work in copper and uranium leaching, and caustic soda brings a stream back up. Dosing is continuous, so batch-to-batch consistency matters more than headline purity.

  • Tailings, water recovery and effluent

    Coagulants and flocculants thicken tailings so water returns to the plant, and neutralising reagents bring discharge back inside a licence limit. On a water-constrained site this is the chemistry with the clearest operating-cost case.

Before you order Mining Chemicals

Which collector suits my ore?

It depends on the mineralogy and the pH your circuit runs at, and no supplier can answer it from a specification sheet alone. Send the ore type, the target mineral and the reagents already in use, and GCS quotes the grades worth trialling rather than guessing at one.

How are mining chemicals packaged for site delivery?

Solid reagents ship in 25 kg bags or one-tonne bulk bags; liquids ship in drums or 1000 L IBCs. The deciding factor is usually what your reagent bay can lift and dose, so tell us that before packaging is quoted.

Can acids and alkalis arrive on the same load?

Often not, and it is never safe to assume so. A spill that mixes them reacts violently and gives off heat, so they are normally kept apart in transport and in storage. What is actually permitted depends on the specific products, their packaging, the route and the rules in force at the destination. Tell us everything on the order and GCS will confirm what can travel together before a delivery window is fixed.

Do cyanide products need special handling on delivery?

Yes. They are transported under regulated conditions, must be received into a secured and bunded area, and need trained personnel present at offload. GCS confirms the receiving arrangements before dispatch is scheduled.
