Here is the answer I sent him: A handheld x-ray fluorescent (XRF) analyzer can reliably identify zinc and lead in few seconds. Handheld XRF technology is a fast and completely non-destructive way to separate these two metals. Without an analyzer, a simple way to sort zinc and lead is to check their hardness. Use a knife to cut — or side ...

problem of sorting lead–zinc ore, new theoretical support is needed. Due to the complex structure of lead–zinc sulfide ore and the distribution of fine-grained minerals, the beneficiation of lead–zinc sulfide ore is difficult. To achieve efficient separation, it is critical to design the separation process based on the characteristics of the

An increase by 4% in zinc production from mine between 2011 and 2012 has resulted in 11% drop in the price of zinc from 2193.9 US$/tonne in 2011–1950.4 US$/tonne in 2012. It has been estimated that, globally, 13.9 million tonnes of zinc has been extracted from mine in 2014 ( World Bureau of Metal Statistics, 2015 ).
