Solution:

Solution given here is very brief. The reader should make attempt to solve the problem.

Charge balance refers to complete details of input and outputs.The amount of inputs and their composition are given. We have to determine amount of outputs and their composition to complete the balance.
Output consists of

i) Lead bullion which is a mixture of

Ag+ Cu + Pb and its amount is 71.16 Tons and consisits of 98.58% Pb, 0.94% Cu, rest Ag

ii) Amount of matte:

iii) Amount of slag:

In lead blast furnace carbon burns at the tuyere level it is important to calculate the amount of carbon burnt at the tuyere level. It can be calculated as follows:

Let X ton moles of  is supplied through tuyeres and y ton moles of co and co₂ exit the furnace.

Oxygen balance









% C burnt at tuyeres level = 90.7%
