Zinc mining in the United States - Wikipedia / The mortality of 4740 male workers of two lead and zinc mines was followed up from 1960 to 1988. Exposure to respirable dust was comparable in the two mines, but the median concentration of silica in respirable dust was 10-fold higher in mine B (12.8%) than in mine A (1.2%), but the mean annual exposure to radon daughters in underground

1.8.2011· The chemical analyses of the Angouran mixed sulphide–oxide lead and zinc ore sample are given in Table 2, and they show that the sample is characterized by a very high Zn and low Pb content. The percentage of the zinc in the oxidised part is 70.5%. This illustrates the importance of the oxidised part of the ore in terms of zinc recovery.
