Question k
Identify two ore dressing processes that are based on different metal properties.
Worked Solution & Example Answer:Identify two ore dressing processes that are based on different metal properties. - Leaving Cert Engineering - Question k - 2007
Step 1
Magnetic properties in magnetic separation
Answer
Magnetic separation is an ore dressing process that utilizes the magnetic properties of certain metals. In this process, ores containing ferromagnetic materials are attracted to a magnetic separator, allowing the separation of valuable minerals from waste materials. This method is effective for extracting iron from its ores.
Step 2
Specific gravity / weight in gravity concentration
Answer
Gravity concentration is a method that exploits the differences in specific gravity or weight of minerals. Heavier minerals tend to settle at the bottom of a mixture, allowing for their separation from lighter materials. This technique is commonly used for gold and other heavy metals.
