Early attempts to devise a blast-furnace process for zinc production failed because of the difficulty of condensing zinc vapour from a gas containing substantial quantities of carbon dioxide. This difficulty was finally overcome in the mid-20th century by the development of the lead-splash condenser, a means of shock-cooling furnace gases and absorbing zinc vapour into solution in molten lead.

The Advantages of Open Pit Mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred method for mining gold, silver, and uranium. This type of mining is also used to dig for coal and building stone.
