Copper-containing compounds are introduced into the environment through agricultural chemicals, mining, and metal industries and cause severe detrimental effects on ecosystems. Certain microorganisms exposed to these stressors exhibit molecular mechanisms to maintain intracellular copper homeostasis and avoid toxicity. We have previously reported that the soil bacterial isolate Achromobacter sp...

The base metal mining sector has been and continues to remain an important endeavour in many parts of the world. The mining of copper, lead-zinc-silver and nickel has led to social and economic development but has also left significant and sometimes lasting environmental impacts. Metal mining is widely perceived to be unsustainable, often without question, since it is drawing down natural capit...

The accurate and precise determination of gold and other precious metals (PMs) is a vital task for companies involved in PM production and the contract or service laboratories that support them. This might involve the processing of hundreds of samples typical of exploration and mining activities, or supplying the quality control assay of the fi nal product from PM producers or recyclers. PMs ar...

Microprocessor Measuring Station (MMS) is a type of programmable logic controller fully developed and designed in Mining and metallurgy institute Bor, Serbia, for monitoring and process control, mainly in copper production plants. It is based on MC68HC11 microcontroller. The paper presents a structure of executive and control program with respect to synchronization of two most important events:...

OBJECTIVE Traditional gold mining is associated with mercury exposure. Especially vulnerable to its neurotoxic effects is the developing nervous system of a child. We aimed to investigate risk factors of mercury exposure among children in a rural mining town in Chile. METHODS Using a validated questionnaire distributed to the parents of the children, a priori mercury risk factors, potential e...

Copper contamination in surface waters is common in watersheds with mining activities or agricultural, industrial, commercial, and residential human land uses. This widespread pollutant is neurotoxic to the chemosensory systems of fish and other aquatic species. Among Pacific salmonids (Oncorhynchus spp.), copper-induced olfactory impairment has previously been shown to disrupt behaviors relian...

Indonesia is a leading producer of wide range minerals, including copper. Nonetheless, the copper-based industry in still not well developed, especially limited number products from intermediate copper which will become raw materials for its downstream industry. The underdeveloped has forced to import several types semi-finished meet needs On other hand, mining exports concentrate and some cath...

The article considers the features of distribution technological indicators (product output, content and extraction copper) by size classes, main factors influencing crushing process are identified regression dependences productivity on received. parabolic nature output crushed rock class is established. high adequacy obtained models was confirmed most promising classes for copper were determin...

Since the early twentieth century, copper-mining industry on Zambian and Congolese Copperbelt has moved millions of tonnes earth dramatically reshaped landscape. Nonetheless, mining companies, governments even residents largely overlooked adverse environmental aspects until 1990s. By scrutinising knowledge production Central African from 1950s late 1990s, particularly regarding notions 'waste',...
