Chemistry for mineral recovery
Products designed around regional mine demand,
qualification and reliable delivery
PHASE 1
CORE PRODUCTS
Sodium Metabisulphite (SMBS)
SMBS is a sulphur-based process chemical used to control oxidation-reduction conditions and suppress or manage selected minerals in flotation and hydrometallurgical circuits. It is also used in certain water-treatment and detoxification applications.
KBMC’s Phase 1 is designed to establish regional SMBS manufacturing, customer qualification and a reliable dispatch platform before the wider integrated build-out.
product overview
Primary use: cobalt processing in mining operations
Market: SADC region
Production method: controlled burning of Sulphur followed by chemical reaction with Soda ash solution
Key features: high purity, consistent quality, reliable supply
Production capacity: 57 500 tons/year
Sodium Xanthates — SIBX, SEX and SIPX
Sodium xanthates are flotation collectors. In simple terms, they help selected sulphide minerals attach to air bubbles so valuable minerals can be separated from waste rock.
- SIBX — sodium isobutyl xanthate
- SEX — sodium ethyl xanthate
- SIPX — sodium isopropyl xanthate
The product mix and capacity will be aligned with customer qualification, operating requirements and demand as the KBMC manufacturing platform develops.
product overview
Primary use: flotation reagent for copper and mineral processing
Market: DRC and Zambia
Production method: on-site carbon disulphide production and reaction with isobutyl alcohol and sodium hydroxide
Key features: pelletised for easy transport and application
Production capacity: 20 000 tons/year
Sodium Hydrosulphide (NaHS)
NaHS is a sulphidising and surface-modifying reagent used in selected flotation and hydrometallurgical circuits. It can support mineral-surface preparation for recovery and the management of certain dissolved metals, depending on the process flowsheet.
KBMC plans to integrate NaHS production with CS₂ and xanthate manufacture as part of the Phase 2 platform.
product overview
Primary use: mining reagent for copper and mineral processing
Market: DRC and Zambia
Production method: hydrogen sulphide gas generation absorbed by sodium hydroxide solution
Key features: crystallisation and flaking process, moisture-resistant packaging
Production capacity: 29 500 tons/year
PHASE 2
Chlor-Alkali Integration
The chlor-alkali plant forms part of KBMC’s Phase 2 integrated platform.
It is planned to produce caustic soda and provide captive chlorine and hydrogen streams required across the wider chemical complex.
