Mineral Technologies adds to MD spirals range with WW7

Mineral Technologies, a Downer company, has added a new spiral separator to its MD range with the Australia-made WW7.

The WW7 are manufactured in the company’s ISO9001:2015-accredited Australian manufacturing facility and shipped to customers worldwide.

Designed with improved wash-water diverters, the new WW7 is great for operations requiring a simpler method of wash-water addition and control, according to the company. It does this with the introduction of a new diverter and secondary wash-water distributor.

Mineral Technologies says customers across North America and Europe are installing banks of WW7s for fine iron ore beneficiation, with the image above showing one of the latest shipments ready to leave the company’s facility.

Mineral Technologies to construct spiral pilot plant at Comilog’s Moanda ops

Eramet’s Comilog SA has awarded Mineral Technologies Ltd a contract for the supply of a fully-equipped spiral concentration pilot plant at its Moanda operations in Gabon.

This plant will be used to recover manganese from tailings produced by Comilog’s various facilities over the years, Eramet said.

“The installation of this unit will be the first step towards Comilog’s training and testing center in Moanda,” it added.

Unveiled in 2014, the Moanda Metallurgical Complex produces two products: silicomanganese, an alloy used in the steel industry containing 69% manganese; and manganese metal, which is found in high-grade steels and electronic devices such as batteries.

The ore is extracted from an open-pit mine on the Bangombé plateau. After extraction, the ore is processed in a facility where it is crushed, ground, washed and sorted, before being shipped to the Moanda Industrial Complex for enrichment.
