Global changes in supply and demand
With the introduction of the Minamata convention there is a need to understand the global changes in supply and demand for mercury.  Current estimates suggest a downward trend in both supply and demand.  The supply of mercury from primary mining has not decreased as much as initially expected.  Indeed, mercury recovery from by-products of nonferrous production has not yet been implemented extensively.   Currently Japan’s small amount of mercury is exported after being refined. In response to an …
Mercury Batch distiller
Managing mercury risk is an important issue for many Australian industrial companies.  Mercury causes very harmful and lasting health impacts due to its toxicity.  The World Health Organisation ranks it in the top ten chemicals for public health concerns. The Minimata Convention, adopted in 2013 is a global health treaty. It was ratified by many countries to raise awareness, and control mercury supply and trade.  Importantly, its aim was to reduce the use and release of mercury into the envir…
Ecocycle continues to invest in mercury waste
Importantly, the Minamata convention became a reality in Australia last year for mercury waste.  This convention was the result of the historical problems caused by the mercury poisoning of Japanese fisherman, who suffered neurological problems.  Mercury and other chemicals were released into the sea near their fishing grounds. Arguably the most toxic chemical to humans, Australia joined 136 other countries in ensuring that mercury could no longer be transported to landfill.  As a result of us j…
Illegal gold mining in Peru results in devastating environmental impacts
The Peruvian government is tackling illegal gold mining deep in the Amazon, where deforestation, mercury contamination and human trafficking have proliferated. For years, miners have defied authorities and unlawfully extracted gold from alluvial deposits in riverbeds, driven by high prices paid for the precious metal. In February, government authorities deployed hundreds of police officers and soldiers to the Madre de Dios region, in southeast Peru, to close down the illicit trade. Whil…
Ecocycle featured in the Australian mining review
Ecocycle was recently featured in the June issue of The Australian Mining Review. Mining waste comes in many different forms, and unfortunately, a large number of its compounds that are extracted are mixed with poisonous materials such as cadmium, arsenic and mercury. Ecocycle works with many of the larger mining waste companies, we also work directly with large industrial clients to help keep hazardous contaminants out of the environment. We are the only company in Australia with the expe…
How Is Mining Waste Recycled?
Mining waste comes in many forms and varies from harmless to highly hazardous. Much of it has little or no economic value but the mining industry is making an effort to find new uses for waste to reduce environmental impacts. And with the prices of commodities moving up and down by large amounts, what may be waste today can suddenly become a valuable resource tomorrow. Here's a quick look at what happens to some of the leftovers of mining and resource extraction.…
Do You Work With Mercury? The Four Things You Must Know About The Minamata Convention
Many people who work with mercury don’t even know it. It is present in fluorescent lighting, some types of dental, medical and mining waste, and in a wide range of industrial equipment. If you have anything to do with these industries, your obligation for their safe disposal is about to increase. We've put together four key things you need to know about Minamata, and what it means for you and your business.   1. The Minamata Convention Keeps Mercury Out Of Our Environment And Waterwa…
Mercury Kills Thousands Every Year. The Minamata Convention Is Here To Change That.
In the mid-1950s doctors in the Japanese city of Minamata began to see patients with severe neurological symptoms. Many died a horrible death. Eventually, Minamata disease was found to be the result of mercury poisoning. A nearby chemical plant was pouring a highly toxic form of mercury, methylmercury, into the sea. Methylmercury is bio-magnified – small fish are eaten by bigger fish, and methylmercury levels increase up the food chain until the big fish are eaten by people. Now, nearly 60 ye…
Mercury Recycling Reduces Mine Risks
We talk a lot about how mercury recycling leads to a cleaner environment by reducing the amount of mercury containing waste that gets thrown away, but recycling also reduces the environmental contamination associated with mining mercury-containing ore (see image) in the first place. Writing in Waste Management World, Christer Sundberg of Swedish company MRT System International AB examines some of the issues.…
