antimony ore valentinite

The ore showed high values of both gold and metallic antimony and fair values of silver In 1905 the shaft depths increased to 700 ft Up to this point the ore was cobbed at the mine with the high grade material being sent to England while the low grade ore remained on site asphalt crushing and screening equipment in malaysia for sale

    Antimony does not often form in its elemental state and is far more common in sulfides and sulfosalts such as stibnite tetrahedrite bournonite boulangerite and jamesonite It is also found in some oxides such as valentinite stibiconite and senarmontite Due to the abundance of these antimony bearing ores and the rarity of native antimony it is never an important ore of itself
