Antimony trioxide - Wikipedia

Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3 is the most important commercial compound of antimony is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis.A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite.

Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids.

Mining | The Canadian Encyclopedia

Apr 07, 2009· Mineral Extraction . Mineral extraction ranges from basic low-technology techniques to massive energy- and capital-intensive undertakings. Historically, "high-grade" ores (containing high levels of target minerals) were mined using simple pick-and-shovel or water separation techniques (pans, sluices, etc.), often by a solo miner or small team.

Lead - Wikipedia

Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element ...
