Metal linked to gold found in central Cuba

HAVANA, Cuba, Oct 19 (ACN) The existence of Tungsten or Wolfram in gold deposits in the Cuban province of Villa Clara, a rare mineral on the planet, is very important due to its characteristics of top hardness and presence in the Melonera-Oropesa strip, detected as a result of the geological investigations carried out.

Orestes Romero, an expert from the Centro Geo-Mining Company, told ACN that Wolfram is an extremely strong metal, which can replace diamond in cutting instruments and is widely used in metallurgy for the production of special steels.
It is of great value in the manufacture of milling machines, drills, hammer-drills and in the electronics industry because it maintains its properties at high temperatures, he stressed.
Romero said that it is a very scarce and expensive metal in the world, where only about 85,000 tons are produced each year (2019), 82 percent of them in China, while Austria is the leader in obtaining it in Europe, with 940 tons.
In Cuba, the only known presence of Tungsten is found on Isla de la Juventud, but in the case of Villa Clara it appears linked to the gold manifestation, which would allow the extraction of the two minerals, if technical and economic conditions allow it, Romero added.
