Extraction of Metals from Ores – Different Processes Involved
Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization. 2. Concentrating the Ore. This step concentrates the ore by performing the removal of impurities. It is also called ore dressing. This process is ...

How to Make a Solution: Chemical, Molar and Weight Percent
Break up hard lumps of chemical with a mortar and pestle or by careful crushing in a plastic bag with a hammer. Chemicals dissolve more quickly by gently heating the solution and stirring. You might consider scaling down when experiments call for large amounts of chemical. Scaling down reduces safety hazards, chemical cost, and waste disposal. Most experiments can be scaled down by dividing ...
