Wodginite is less common, but was the primary tantalum mineral found in the original Wodgina deposit in Australia (from which it gained it name) and also at the Tanco mine in Canada. Struverite, a variation of rutile, is a low grade source of tantalum predominately associated with cassiterite (tin ore) in .

2 Mineral-Deposit Model for Lithium-Cesium-Tantalum Pegmatites cesium, and tantalum are generally concentrated), and core. This zonation is expressed both in cross section and map view; thus, what may appear to be a common pegmatite may instead be the edge of a mineralized body. Neither lithium-cesium-tantalum pegmatites nor their

R's expertise lies in Military and Industrial grade Tantalum products and capacitor grade Tantalum powder. In addition, we trade raw minerals such as Ta2O5, WO3, and Co Hydroxide. Recently, we have expanded our business in chemical trading such as high purity SiO2 and BaSO4.

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.. The ore grade, or concentration of an ore ...

Another benefit to Morefield mine tantalum is its origin in the USA guarantees it is 'conflict-free' and the cost of guaranteeing the chain of ownership is minimal compared to African tantalite. Tantalum concentrate/ore is often referred to as 'Coltan'.

Trading Tantalite (coltan) concentrate and ore from Central Africa and South America. Tantalite Specifications. Tantalite traded on the international market typically contains a minimum of 30% Ta2O5. Lower grade material, minimum 20% Ta2O5, is also traded but at a discount. Tantalite is purchased and sold solely on it's Ta2O5 content.

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

Coltan (short for Columbite-Tantalite and known industrially as Tantalite) is a dull black metallic ore from which the elements Niobium and Tantalum are extracted. The Niobium-dominant mineral in Coltan is Columbite (after Niobium's original...

due to the refractory nature of tantalite, and XRF due to the typically low natural tantalum abundances. Our laboratories use fusion ICP-OES or fusion ICP-MS to ensure both a low detection limit and total analysis.

The geological and mining work done confirms a 100 000t ore resource in place and the potential for a further 1mn tons across all the claims. Geological drilling work has been carried out and a proven resource of 100 000 tons of Ta2o5 has been identified across 3 adjacent ore bodies. The average tantalite grade ranges from 250g/t to 450g/t.

The Mine has one of the highest grades of tantalum ore in the industry. In 2017, the company signed a multi-year supply agreement with the leading global North American tantalum consumer and end user of our tantalum ore. Aftan is exploring further opportunities to supply additional customers as .
