Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities. Gold is often associated with PGM deposits and treated as part of a family — with Platinum, Palladium and Rhodium —collectively known as "4E".

testwork, to develop a complete process flowsheet based on smelting operations as soon as the elemental analysis of the feed is known, on the contrary it is absolutely required to perform preliminary laboratory testing whenever the flowsheet involves mineral proces­ sing operations. In contrast to smelting, which has an effect of

Dive deep into your workflow. Go in-depth and map out every step, task, and activity in your workflow with an online process flow diagram. Start inspired with free templates from Canva Whiteboards, add shapes and icons to represent each step, and then connect parts to show relationships between tasks. Go beyond simple text and arrows—use our ...
