Extractive Metallurgist Career Description
Extractive metallurgists are involved with the recovery of useful metals or minerals such as gold, coal, diamonds, copper and iron, from the ore bodies in which they occur.
What am I going to do in this occupation?
After a foundation in physical science has been established, the field of study branches into the following:
» Ore preparation: extraction and separation processes are based on the chemical and physical properties of the material, such as density, size, magnetic properties, etc.
» Pyrometallurgy: processes are based on the heating and smelting of materials in order to extract the valuable metals.
» Hydrometallurgy: processes are developed to work with and recover metals in solution.
Some ore bodies contain as little as 5 grams per ton (5 parts per million) of a precious metal. Extractive metallurgists are required not only to recover these small amounts of material but also to do so in the most economical way. This will become even more important in the future.
They must also have a detailed understanding of physical and chemical characteristics of metals and minerals. They will need to use this knowledge to design, test, operate and maintain processes and plants to extract and separate these metals and minerals. Because of the need to recover as much of the mineral as possible, modern plants use the latest instruments and computers to help monitor the processes and pinpoint problems on the plant as soon as they occur. Hence metallurgists also need to be familiar with these control and monitoring systems.
Requirements
What kind of personality do I need?
A mathematical aptitude and scientific interest are important for extractive metallurgists. Insight, logical thinking, well-developed problem solving skills and self-discipline are also important qualities. An ability to work with and to lead people, as well as good communication skills are essential.
Where can I work?
Most major companies offer accredited
training programmes to help new graduates to develop their practical skills. Thereafter graduates can be appointed as extractive metallurgists at a
plant or installation where they can gradually be promoted to the management level. They can also choose a career in research where they start as researchers in a metallurgical laboratory from where they can move into the several specialist fields. Mining companies usually use graduate extractive metallurgists or process engineers to implement new developments.
Can I work for myself in this occupation?
Suitably qualified and experienced metallurgists can establish themselves as independent consultants offering, specialist advice and service to metallurgical plants and companies.
