verderflex peristaltic hose pumps - mining applications

VerderMining Applications

PAUL NELSENMANAGING DIRECTOR

Thickener Underflow

• Peristaltic pumps handle high specific gravity associated with thickener underflow slurries, which centrifugal pumps cannot handle.

• Improvement in thickener performance

Dosing Flocculant (SIBX)

• Maintain particle size

• Less chemical needed

First Quantum Minerals

• Four VF125 hose pumps installed on two thickeners for underflow circulation

Kansanshi Copper Mine, Zambia

Platinum Slurry

Dosing Systems in Lead Mining

• CuSO4 , NaCN & Na2Cr2O7 at Lead Mines in the Andes

Mining Slurry

•VF100s used to pump thickener underflow slurry

•Slurry has 80% inorganic solid content

•Other reasons for selection: – Abrasive nature of slurry– Low maintenance costs

BHP Cannington, Australia

BHP Cannington, Australia

• Lead Slurry being pumped by flow-paced VF125

BHP VF125 Thickener Installation

Cyanide Dosing in Gold Spoil Heap Leaching Recovery

•Customer pumps Cyanides onto gold mining waste to recover 99.9% of “lost gold”•Key reasons for selecting Verderflex pumps – No seals, consistent dosing, chemical resistance and solid content of dosed chemicals

Mining Drill Unit

•Verderflex VF50 replaced submersible pump due to high maintenance costs

•Same customer bought three VF125s

Drill Bit Dewatering & Cooling at Olympic Dam Mine, Australia

•Additional benefits were safety (no metal to metal contact to create an explosion risk), insensitivity to debris in pumping lines, abrasion resistance, and suction lift
