Mining
Every mine runs a sequence of circuits — crushing, grinding, leaching, flotation, refining, tailings. Each has a predictable consumable bill. Olfa supplies across all of them, in every major commodity stream we serve.

Supplying Across the Mine
From grinding media and bulk reagents through flotation chemicals, leach accelerators and tailings detoxification — Olfa supplies the consumables and bulk inputs that keep a mine running. We work with operations at any scale, from first enquiry through multi-year supply agreements.
The sub-pages below are organised by commodity, because that is how a metallurgist thinks about their plant. Within each, we map what we supply to where it goes in the process.
Built to win the tender, not just the line item.
A mine does not want twelve suppliers and twelve risks. It wants one accountable partner who can land the whole consumables basket, on spec, on time.
01
One basket, one PO
Fuel, reagents, grinding media, mill and crusher liners, screens and explosives precursors — consolidated under a single supply agreement with one point of accountability and budget certainty.
02
African logistics, solved
International procurement through in-country delivery: cross-border clearance, bonded warehousing and last-mile haulage to remote sites where most traders stop at the port.
03
Compliance, documented
Certificates of Analysis, SDS, Certificates of Origin and third-party inspection on every consignment — the paperwork that clears customs and satisfies the technical evaluation.
04
Working-capital terms
Framework pricing and credit terms structured around the mine's production schedule — turning procurement from a cash drag into a managed, predictable flow.
