GIW Froth Pump Prevents Airlock Shutdowns at Mondo Minerals Talc Plant

By: KSB

In operation at the Mondo Minerals talc plant, the HVF model pump increased talc production by 5,000 metric tons in its first month of operation.

GIW Industries, the leader in the design, manufacture and application of heavy-duty, centrifugal slurry pumps, announced that global talc producer Mondo Minerals has installed GIW’s High Volume Froth (HVF) pump at its talc processing plant in Outokumpu, Finland. During the pump’s first month of operations, the plant was able to stabilize the flotation process and eliminate a safety hazard.

No matter how you handle it, airlocking means production losses
Mondo Minerals’ talc processing plant had a froth-pumping problem. The high air content in the froth caused airlock in its previous slurry pump, which resulted in overflow of the pump sump. This caused an unbalanced process and decreased productivity at the plant. This, in short, led to lost profitability. And to make matters worse, the operating losses were happening when the plant was running at maximum output.

Operators tried various approaches to reduce the slurry pump airlock: they modified the sump and the inlet pipe to the slurry pump and installed spray nozzles to reduce the froth in the sump. However, modifications were ultimately ineffective.

A solution appears — through the grapevine

Installed HVF Pump

As a world leader in the talc mining industry, Mondo Minerals was aware of the success that had been attained by Yara, a phosphate plant also located in Finland. Upon learning that Yara had solved a similar froth problem by installing GIW’s HVF pump, Mondo decided to install an HVF in its own plant.

Erkki Kohtanen, GIW business development manager for North America and Nordic countries, explains that this type of word-of-mouth marketing has been the primary means of spreading the word about GIW’s HVF pump in Nordic countries.

“This pump is doing its own marketing work,” Kohtanen says. “Mining professionals around the world are spreading the word about the results that are possible with GIW’s HVF pump.”

Immediate, dramatic results

As soon as the GIW HVF pump was installed, the Mondo plant got the ROI it had hoped for.

Within the first month of the pump’s operation, Mondo increased its productivity. Plus, Mondo realized a substantial cost savings with the reduction of required fresh water. All this was achieved because the HVF pump does not airlock, allowing the customer to operate a balanced flotation process.

In addition, now that the sump is not overflowing periodically, Mondo has eliminated the slip hazard, improving the work environment for its employees.

Mondo Facility

Kohtanen reports that the Mondo pump is operating at 250 cubic meters per hour and producing 18 meters of head — supporting an improvement in overall plant efficiency. For the talc producer, that improvement means a significant increase in profitability, as its high-quality talc is used around the world in a myriad of industrial applications.

“The plant manager is very happy about this pump!” Kohtanen says. He adds that, based on the extremely positive experience at the Finland plant, Mondo intends to proceed with further installations at other plant locations.

“Mondo is excited that they see multiple applications for this pump,” Kohtanen says.

About GIW Industries

GIW Industries began as a small foundry and machine shop in Augusta, Ga., in 1891. In 1914, GIW began building slurry pumps. Today, the company comprises two manufacturing facilities, one in Grovetown, Ga., and the other in Thomson, Ga. These foundries and machine shops are used for manufacturing and assembling pumps and for casting a variety of abrasion-resistant alloys and urethane elastomers. As a subsidiary of KSB AG of Germany, a global pump and valve manufacturer, GIW has the infrastructure to supply pumps worldwide. KSB has presence in 100 countries with sales organizations, offices and 30 manufacturing sites.
