This document contains important information on the definitions and descriptions of terminologies in economic geology.

starts by defining industrial chemistry and then gives a view of the chemical industry, its position in the general economy, and its classification in terms of the chemical processes that characterize it. To enable the study of selected chemi cal processes, unit operations and unit processes, especially those that are relevant in later learning actvities, are then covered in Unit 2. With this background, it will be easy to study industrial inorganic and organic chemical industries. The ...
