Xrd Method

Hydrogen peroxide is used to extract uranium by the in situ leaching of sandstone ore deposits containing uraninite (UO2). Since FeS2 minerals, marcasite and pyrite, also occur in these deposits and they consume hydrogen peroxide in their oxidation, it is important to determine their concentration.A quantitative X-ray diffraction (XRD) method was therefore developed in order to monitor the concentration of marcasite and pyrite in sandstone ores.

The Shidi Pb-Zn deposit is located in Xiushan County, southern Chongqing, and its orebodies were hosted in marine carbonates of the Cambrian Pingjing Formation. The authors selected sulfide minerals from the deposit for the analysis of sulfur and lead isotopic compositions. Theδ34S values of sulfide minerals vary from 10.8 to 15.6, with an average value of 13.52, indicating these sulfide materials were mainly derived from marine sulfate reduction. The 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios for sulfide minerals vary within the ranges of 18.319~18.422, 15.740~15.784 and 38.355~38.511, respectively. In the diagrams of Zartman, the Pb isotopic compositions of sulfide minerals fall into the regional upper crust lead zone. According to the characteristics of sulfur and lead isotopic compositions of the Shidi Pb-Zn deposit, the ore-forming materials might have come from the black shales of the Lower Cmabrian Niutitang Formation.

The pollution status of ten potentially toxic elements (PTEs), isotopic compositions (Cu, Zn, Pb), and the potential ecological risk posed by them were investigated in the PM10 fraction of road dust in Busan Metropolitan city, South Korea. Enrichment factors revealed extremely to strongly polluted levels of Sb, Cd, Zn, Pb, and Cu in the PM10 fraction of road dust, with Sb levels being the highest. Statistical analyses showed that the major cause for contamination with PTEs was non-exhaust traffic emissions such as tire and brake wear. Cu and Zn isotopic compositions of road dust were related to traffic-related emission sources such as brake and tires. Pb isotopic compositions were close to that of road paint, indicating that Pb was a different source from Cu and Zn in this study. No significant health risk was posed by the PTEs. Taking into account the total length of road in Busan, a high quantity of PTEs in road dust (PM10) can have serious deleterious effects on the atmospheric environment and ecosystems. The results of metal concentrations and isotopic compositions in road dust will help identify and manage atmospheric fine particle and coastal metal contamination derived from fine road dust.

Polymetallic Ore

In the Danchi mineralization belt of Guangxi province, south China, the Dachang tin-polymetallic ore deposit is one of the largest Sn ore deposits in this world. But about the genesis and the ore source, there have been some disputes. In terms of the Dafulou deposit, the mineralization model and deposit mechanism is rather illegibility. By analysing and comparing the lead isotope of three ore deposit (the Changpo, the Lamo and the Dafulou), it show that the correlations of 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb of sulfide minerals demonstrate obvious excellent linear relation. So, it is also suggested that the eastern mineralization belt, the middle mineralization belt and the western mineralization belt shared the same ore source. And, according to the features of no.22 ore body, the Dafulou deposit is characterized with the characteristics of the Sedimentary Exhalative Deposit (SEDEX).
