Roasted lead ore with composition: 25% PbO, 18% PbS, 22% Fe2O3, 2% Cu2S, 29% SiO2, 4% CaO is smelted using CaCO3 as a flux to obtain a slag containing 18% Cao. Coke containing 85% C and 15% SiO2 is used as a fuel by 20% of ore weight. 5% of Pb is lost in flue gases and its 8% is transformed to matte. Half of Cu is found in matte and the other half in lead ore. 10% of S is lost as flue gases. For 1000 kg of ore, 1. Determine the weight of Pb metal. 2. Determine the weight of matte. 3. Determine the weight of CaCO3 added.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
