How Installing Arsenic Drinking Water Treatment Can Save Your Life

Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

Mining water from gypsum

Water resources in the world are scarce and unevenly distributed. In deserts, the only source of drinking water is groundwater, often saline and of poor quality. In many places, the groundwater levels have dropped dangerously due to overexploitation. Gypsum deposits, that are very common in deserts, are a potential source of drinking water, a fact that is realised by very few people. Gypsum ...

Mine backfill

Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

Sustainable mining

It's imperative that natural resource industries adopt a proactive (even aggressive) approach to the disposal and management of their wastes. Operators must challenge themselves to raise the bar in terms of environmental performance not only to meet the expectations of regulators today (and investors and the general public), but in the future, when requirements will no doubt be even more ...

Mining, the environment and the treatment of mine effluents

The environmental impact of mining on the ecosystem, including land, water and air, has become an unavoidable reality. Guidelines and regulations have been promulgated to protect the environment throughout mining activities from start-up to site decommissioning, in particular, the occurrence of acid mine drainage (AMD), due to oxidation of sulfide mineral wastes, has become the major area of ...

Open water spill at Kemess Mine in Canada

We received a request for SpillRemed (Industrial) from Kemess Mine located in the rocky mountains in Canada. The mine was so inaccessible that it took almost 10 days for the shipment to reach the customer. The company had a diesel spill in the containment berm and as per the standard protocol absorbent booms were placed to recover the spill, but unfortunately the boom absorbed water and sank at ...

Water supply and mining: the policy paradox in Ghana

Ghana has been highly successful in mining for over a century. However, one area of concern is the negative impact of mining activities on water resources: their quality and quantity. Mining companies are guided by rules and regulations, particularly those that have to do with the quality of water supply. Safe water supply is essential for improved health and quality of life for increased ...

Are mining waste disasters inevitable?

On 5 November 2015 the dam of an iron ore tailings management facility in Bento Rodrigues, Brazil, suffered a catastrophic failure and flooded the area. The immediate consequences were dire: the accident killed at least 11 people, injured over a dozen more and left more than 500 people homeless. However, this is just the start: the environmental impact of the Bento Rodrigues dam disaster, with ...

Comparison of Gas and Water Pycnometry of Coal Mine Wastes

Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

Optimising the Rehabilitation of polluted Mine Tailings and Water by SupaZorb

To date the polluted acid mine drainage (AMD) – the second biggest environmental problem of the world - from South Africa’s gold mines, was characterised and treated by the precipitation of heavy metals with lime and sulphates, by means of iron exchange. The chemical treatment with expensive and toxic caustic soda (Sodium Hydroxide, NaOH) is to lift the pH, in order to reduce the corrosion on ...
