Galena, the most common mineral of lead, is primarily lead sulfide (PbS). The sulfide is oxidized to a sulfite (PbSO 3 ), which thermally decomposes into lead oxide and sulfur dioxide gas. (PbO and SO 2 ) The sulfur dioxide is expelled (like the carbon dioxide in the previous example), and the lead oxide is reduced as below.

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

This bead of lead was created by two students, Katie Davidson, 11, and Elliott Smith, 14, at the Bishop Bell school in East Sussex. They heated yellow lead (II) oxide with powdered carbon in a test tube, resulting in the reduction of the oxide to the base metal, which was poured out while the tube was still hot.

Fig 3 Leady Oxide SEM images from the ball mill process. The principle of oxide production for either of these methods relies on the surface oxidation of lead particles. These particles are molten droplets in the case of a Barton pot (Fig 2), and solid flakes in the case of a ball mill (Fig 3).

1. Introduction. Zinc oxide, with its unique physical and chemical properties, such as high chemical stability, high electrochemical coupling coefficient, broad range of radiation absorption and high photostability, is a multifunctional material [1,2].In materials science, zinc oxide is classified as a semiconductor in group II-VI, whose covalence is on the boundary between ionic and covalent

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

Some pigments are soft and can be damaged by milling, especially when placed in a ball mill for extended periods of time. Another important point to consider is the pigment''s solubility and what effect the solvent will have on the pigment''s hardness and structure.

Zinc oxide has also been precipitated from aqueous solutions of zinc chloride and zinc acetate . Controlled parameters in this process included the concentration of the reagents, the rate of addition of substrates, and the reaction temperature. Zinc oxide was produced with a monomodal particle size distribution and high surface area.
