Ukraine-based mineral sands

Ukraine-based Velta has placed an order with Multotec for the supply of NHM and SC20 spiral concentrators to process minerals from an opencast operation in the Birzulovo ilmenite deposit in South Ukraine. Delivery is scheduled for the end of October 2011, and Multotec engineers will be deployed to the site with representatives from Multotec’s local distributor, DIN, to supervise installation and commissioning.

Dean Lincoln, general manager – marketing and business development at Multotec, said: “This is one of the biggest projects of its kind in the country in recent years and is being supervised by the new government of the Ukraine to revive its national mineral sands sector. A recent order from India for a similar industry, together with this prestigious order from Velta, has firmly positioned us as one of the leading players in the international heavy mineral and minerals sands markets. “The Multotec NHM spiral was developed specifically to treat low grade mineral sands. It is one of our latest offerings for maximum recovery of heavy minerals.” The Multotec NHM spiral is a modification and replacement of the previous SC22 spiral.

The pitch of the Multotec NHM spiral is shallower to accommodate low grade heavy mineral sands. With a trough of 700mm diameter, the spiral has the capacity to handle between 1 to 2.3t/h dry solids tonnage at a weight solids dilution of 30-35%.

The largest rare earth reserves are found in China

The largest rare earth reserves are found in China, later followed by the United States, Australia and India. In China and the United States, the rare earth substance is contained in bastnaesit, which constitutes the largest resource component. The other substantial rare earth resource in the Bamboo Curtain Country results from absorption ore deposits of lateritic ion, which constitutes mustiness of granitic and sientic rocks in tropical regions, mainly southern China, while the resource in Brazil, Malaysia, Sri Lanka, India and South Africa as well as Thailan results from monazite mineral inside secondary deposits. In Indonesia, the rare earth minerals are found along the tin lane in Bangka-belitung as well as gold lane in Kalimantan. In West Kalimantan, the minerals associate with uranium deposits. Data at the Geology Resource Center 2007 show that the monazite ore deposits in Indonesia total 185,992 tons. The potential is located in tin producer regions. In line with the rising exploration of tin, monazite deposits also increases. However, the quantity has not been known exactly. Globally, the monazite deposits are estimated at 12 million tons and two thirds of the total constitutes heavy mineral-sand deposits in India’s eastern and southern coast. Studies carried out by the Geology Research and Development Center of the Energy and Mineral Resource Ministry (KESDM) show that rare earth is also associated with uranium ores of the monazite type. The study has been applied to uranium ores in Rirang, West Kalimantan Barat. Study executed in Bangka Barat also finds rare earth substances Niobium and Tantalum. In the meantime, study in Kuala Kampar, Riau shows that there are several rare earth minerals, such as tantalum, zirkonium, neobium and yttrium. The existence of the rare earth minerals in the region is closely related to the tin deposits in Sumatra. Kampar and Bengkinang, Riau, kasiterit as the main product of tin mining with associated rare earth minerals, such as monazite, xenotim and zirkon are found. Source : majalahtambang.com

Banro Corp Report from Twangiza

Processing Loading & Hauling Crushing & Conveying Drilling & Blasting Banro Corp has announced that the structure of its altogether-owned Twangiza Step 1 nugget enterprise in South Kivu Field, DRC, is affair on list along nugget output prospective to originate in the December coin of this year. 'Freezing commissioning' - a ordeal score of juices per the mineral processing perennial - has instantly commenced beside perfunctory commissioning that resolution wend to 'heavenly commissioning' - a try rush of filthy rank mineral information around the cultivate - by mid-September. Simon Home, Banro’s CEO commented: "We are prompt approaching a momentous plateau for both Banro moreover South Kivu area in the DRC. Whereas Banro's Lodge made the opinion to emanate beside progress of Twangiza in 2009, we possess worked diligently to a promiscuous agenda which has allowed our troupe to gush its leading nugget in couple years, further accompanying weeks to go, we linger on inventory. “This occasion choose also siren a tremendous feat for the South Kivu field as it determination be the introductory unfamiliar mercenary nugget explosive in the DRC for beyond part a age - plus a will to the co-agency beside the neighborhood, rule also commerce which was integral for this enterprise." Activation of the 1.3Mt/y nugget output skill emulates 24 months of tough deadlines which contain been systematically achieved starting among the perennial point besides structure shelter secular excavation processs that were completed pair months forward of card. The annual talent is planned to be increased to 1.7Mt/y by mid-2012. Cultivate respectful structure processs are almost finish during the structural, perfunctory, electrical, instrumentation furthermore piping are circa 93% end. The diesel-powered Aggreko weight cultivate along a map endowment of 7MW is 90% unabridged moreover a informant of inexperienced moisture for the processing annual has been secured.
