The best known precious metals are gold and silver. Although both are used in industrial applications, they are better known from art, jewellery and coinage. Other precious metals include the platinum group metals (PGM’s): ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.

Accurate exploration of ore bodies and frequent monitoring of the mineral paragenesis are essential to make the extraction of the precious metal profitable. Slightly higher recovery rates of the precious metals give an enormous increase in the value of the deposit and final products. 

Preg-robbing (the absorption of precious metals by carbonaceous components in the ore) is a well-known challenge during leaching. Modern analytical solutions enable monitoring of the mineral composition and zeta potential of the ore at an early stage. This can make immediate counteractions possible to prevent preg-robbing.  

Malvern Panalytical offers innovative solutions to meet the industry requirements and provides the right analytical tools for geologists, process control operators and geometallurgists.
