Background

Silver naturally occurs in various ore and minerals, often as sulfides or chlorides or in combination with arsenic or antimony. A main source of silver is found in copper ore, as well as in copper-nickel, gold, lead and lead-zinc ores. Silver and other precision metals are also reclaimed from tailing piles or other recycled ore materials that would previously be discarded. Therefore the silver must often be measured at relatively low levels, as low silver levels can be considered profitable to extract. To meet the challenges of low level silver analysis in ore and ore materials Rigaku offers the NEX DE EDXRF analyzer with 60 kV excitation source and high throughput SDD detector capable of yielding 500,000+ cps, giving the analyst and technician alike a fast, simple, yet powerful means for measuring elemental composition.
