2018 9 5ensp;0183;ensp;Lead is a chemical element with 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 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

Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 176;C (621 176;F), coupled with its easy
This is when solid particles stick to one another, and while this is an undesirable feature in many powder and particle processing operations, it is essential for the successful sintering of iron ore fines, coke and fluxes into a suitable blast furnace feed.
2018 8 24ensp;0183;ensp;An ore is an 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 from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore
