If a rock of lead ore contains 84% by mass PbS. How many ...
Answer (1 of 3): First we should get the molar mass of PbS which is lead 207.2 plus S_{32} so we get 239.2 gram/mol. Then we get the mass percentage of Pb in PbS so 207.2 / 239.2 x = 86.62% Then to get the required 2.5kg or 2500grams, we divide this by the mass percentage of Pb in PbS then...

A 1.362 g sample of an iron ore that contained Fe3O4 was dissolved in acid with all of the iron being reduced to iron (II). The solution was acidified with sulfuric acid and titrated with 39.42 mL of 0.0281 M KMnO4, which oxidized the iron (II) to iron (III) while reducing the permanganate to manganese (II).

Metal Profile: Iron Properties and Characteristics
History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

Iron ore - Wikipedia
Rich iron ore contains more than 57 % iron, less than 8–10 % silica, less than 0.15 % sulphur and phosphorus. It is a product of natural enrichment of banded iron formations originated by leaching quartz and decomposition of silicates during long-term weathering or metamorphosis. Lean iron ores may contain 26 % iron min.

Products Made from Iron Ore
Iron ore is primarily mined and refined through a process called smelting. Smelting is a heating process in which the Iron ore is heated along with coke (charcoal) and limestone in a blast furnace. The heating process melts the iron contained in the mixture and eliminates much of the carbon that is contained. Using variations of this process ...

Understanding Iron Ores and Mining of Iron Ore – IspatGuru
Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.

iron processing - Ores | Britannica
As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.
