Mining activities have resulted in a large volume of tailings containing certain proportion lost minerals, making them potential reprocessing opportunity, and information on mineral is often scarce. In this study, conceptual framework was established used to produce meaningful knowledge from the Nyamatete mine at HABATU Company Limited (an ASM Rwanda). Tailings particles were investigated based...

Microbacterium sp. strain SZ1 isolated from gold ores of a Malaysia gold mine was found to be highly resistant to arsenic. Here, we report the draft genome sequence of SZ1, which may provide further insights into understanding its arsenic resistance mechanism. In this draft genome, a complete set of ars operons and two additional scattered ars genes were encoded.

widespread arsenic contamination of mining wastewater of zarshouran (west azerbaijan province) hasled to a massive epidemic of arsenic poisoning in the whole of surrounding areas. it is estimated thatapproximately all agriculture fields are being irrigated with the water that its arsenic concentrationselevated above the world health organization’s standard of 10 parts per billion. a novel advan...

• Importance of investment and mechanization in ASM operations. Relevance distinction between 'artisanal' 'small-scale' mining. Processing equipment technology allow for economies scale. Innovation brings deeper deposits within the reach operators. In South Kivu Province eastern Democratic Republic Congo, use new technologies artisanal small-scale gold mining (ASGM) has proliferated over course...

Gold refineries are under pressure to revise their understanding of “integrity” beyond the physical cohesion gold products, in order integrate supply chain due diligence on human rights, labour conditions, and conflict financing as part what can be coined ethical integrity gold. This article interrogates how processes erasure, through material purification refining process, disclosure, certific...

How Mining Releases Toxic Metals Large amounts of waste rock and tailings contaminated with toxic metals can be produced by mine sites. In the case of the Donlin Creek mine, there are only 0.072 ounces of gold for every ton of ore, a figure that does not take into account the waste rock. Toxic substances contained within the rock and tailings are more easily released once these substances are p...

Mine water contains trace heavy metals which are some essential elements in high concentrations causing the pollution of nearby bodies, related ground waters and soils degradation. The aim study is to identify quantify present different mine samples their level toxicity. Digestion technique was employed pretreat wastewater before analysis. Physicochemical analysis conducted for pH, electrical c...
