Platinum (Pt) is a rare and valuable metal that is widely used in various industrial applications due to its unique properties. Platinum ore refers to the naturally occurring rocks or minerals that contain significant concentrations of platinum, usually in the form of platinum group minerals (PGMs) and associated minerals. Platinum ore is …

The steel production process is a multi-faceted journey that begins with extracting and processing iron ore, a primary raw material essential to steel making. Iron ore undergoes a series of refining steps to extract the iron content, culminating in the creation of molten iron. This molten iron is then subjected to steel melting, a critical ...
