Substantial Variability of Multiple Microbial Communities
Deep sequencing of prokaryotic 16S rDNA regularly reveals thousands of microbial species thriving in many common habitats. It is still unknown how this huge microbial diversity, including many potentially competing organisms, may persist at a single site. One of plausible hypotheses is that a large number of spatially separated microcommunities exist within each complex habitat. Smaller subset

Minerals Free FullText Sequential Bioleaching of Pyritic
In this work, we proposed a method for biohydrometallurgical processing of mining (old pyritic flotation tailings) and metallurgical (slag) wastes to recover gold and other nonferrous metals. Since this processing allows the removal of toxic metals or at least decreases their content in the solids, this approach may reduce the negative environmental impacts of such waste. The proposed process

Microbiology of diverse acidic and nonacidic microhabitats
12, 2012 · A wide variety of microhabitats within the extremely acidic abandoned underground copper mine Zlaté Hory (Czech Republic) was investigated. SSU rDNA libraries were analyzed from 15 samples representing gossan, sulfideleaching environments in the oxidation zone, and acidic water springs in the mine galleries. Microbial analyses were extended by analyses of chemical composition of water and

Extreme environments: microbiology leading to specialized
In general, extreme acidophiles can be defined as microorganisms that grow optimally at pH values below 3 (Johnson and Quatrini 2016). These microorganisms are common in acid lakes, acid sulphate soils and acid mine wastes (Druschel et al. 2004Mirete et al. 2017).

Introduction. Brazil is the world's 15th largest producer of copper concentrate. 1 The mining company Vale S.A. is responsible for the majority of copper production, having reached 275,000 mt of copper concentrate in the first nine months of 2013, 2 and operates at the Sossego Mine (Canaã dos Carajás, PA, since 2004) and at the Salobo Mine (abá, PA, since 2012).

Geomorphology of old and abandoned underground mines: Review
May 18, · ÁlvarezVigil et al. (2010), Gayarre et al. (2010) and Herrera et al. (2012) monitored the ore mine in the La Unión municipality in southeastern Spain, where excavation took place from Roman times to the early 20th century. This area was urbanized despite the warning issued by the Spanish General Board of Mining at the end of the 1970s.

Acidic Environments
04, 2018 · Acidophiles have been the focus of substantial research in recent years, particularly regarding their role in acid mine drainage. One of the most wellknown acidophiles with respect to this important environmental problem is Ferroplasma, which was found growing at pH 0 in acid mine drainage in Iron Mountain in California.
