Caulobacter vibrioides T5M6 is a Gram-negative strain that strongly solubilizes selenium (Se) mineral into Se(IV) and was isolated from a selenium mining area in Enshi, southwest China. This strain produces the phytohormone IAA and promotes plant growth. Here we present the genome of this strain containing a large number of genes encoding resistances to copper and antibiotics.

Here we introduce a combined experimental and descriptive approach (termed resurrection ecology) to reconstructing historical perturbations, pointing out how direct tests with sediments and hatched resting eggs complement the traditional descriptive calculation of microfossil fluxes. In the Keweenaw Waterway, a freshwater estuary off Lake Superior, turn-of-the-century copper mining impacted the...

Angelovičová L., Fazekašová D. (2014): Contamination of the soil and water environment by heavy metals in the former mining area of Rudňany (Slovakia). Soil & Water Res., 9: 18–24. Contamination of soil and water environment by heavy metals in a former mining area and their effect on the soil characteristics were determined. Soil samples were collected in the village of Rudňany which is, accord...

Heap bioleaching processes are of increasing interest in the mining industry to recover metals from secondary ores. Recently, it has been proposed to use feedback control to improve the rate of mineral extraction. In this paper we compare two feedback approaches, namely Model Predictive Control (MPC) and Extremum Seeking Control (ESC), to improve copper extraction in a heap bioleaching process....

1. Introduction Thompson-Okanagan-Cariboo is an administrative region in south-central BC, established after the province reorganized its natural resource agencies in 2010. Mining predates Confederation and today, the region is home to fi ve of BC's largest metal mines, several industrial mineral mines, and many small placer operations, gravel pits, and rock quarries. power), and skilled worker...

Since 2005, the mining sector has been a vital part of Mongolia's economy. This is one most important sources revenue. Primary outputs industry are copper, gold, and coal. On other hand, negative impact on environment causing soil erosion, noise pollution, water biodiversity loss. The Oyu Tolgoi copper mine located in semi-arid zone Mongolian Gobi. was investigated by sampling eight plots both ...

Most of the work which has been done on trace elements in soils has been in relation to deficiency or toxicity effects on plants. Although a certain amount of work has been reported on the effects of trace elements on ammonification and nitrification in soils 12 a 4 5 6 the results obtained are conflicting. Trace elements may be introduced into soil where pesticide sprays e.g. copper fungicides...

Concentrations of copper, arsenic and cadmium in sediments and soils deposited on the flood plain of the upper Clark Fork River drainage were determined to be one to two orders of magnitude greater than in soils from typical noncontaminated systems. Aerial deposition of metal particulates during the period of smelting activities (1884-1980) has contributed approximately 2% of the excess copper,...

BACKGROUND The metal mining industry employs approximately 15% of formally employed workers in Zambia, but there is little information about the magnitude of occupational injuries among the miners. AIMS To determine the frequency rates of occupational injuries and fatalities among copper miners in Zambia. METHODS A retrospective study of occupational injuries and fatalities at one of the la...
