How to Control Use of a Group Lockout Box for Isolations
Instead of each team member applying their locks on a specific energy isolation device, using group lock box now enables the team to apply just one lock on each energy source. The keys of these security locks can then be stored in the group lockout box. Authorised employees can now apply their personal security padlocks on the group lockout box.
Monitoring of a Platinum Group Metal Flotation Plant with an Isolation …
Froth flotation is one of the most important techniques in mineral processing to beneficiate valuable minerals from ore. As a consequence, advanced control of industrial flotation plants can significantly affect the efficiency of mineral beneficiation. Videographic monitoring of flotation cells is a vital element of advanced process control systems, as the froth …

Platinum Group Elements | SpringerLink
Platinum group elements are ruthenium, rhodium and palladium (of similar weight as, but lighter than silver, the next element in the periodic table by atomic number) and osmium, iridium and platinum (of similar weight as, but lighter than gold, the next element in...
WebElements Periodic Table » Platinum » the essentials
Platinum: isolation. Isolation: it would not normally be necessary to make a sample of platinum in the laboratory as the metal is available commercially. The industrial extraction of platinum is complex as the metal occurs in ores mixed with other metals such as palladium and gold.
Directing Group Strategy for the Isolation of …
The exploration of fourth-period organoelements, particularly organoseleniums in their highest VI oxidation state, is limited owing to their stability and synthesis. Herein, the isolation of a new class of quinolinyl-embedded, hexavalent selenium(VI) benzoselenonates has been discussed and further evaluated for a metal …
