Gold tailings: Xinhai usually use all slime cyanide process and carbon in pulp process to recover the gold from gold tailings As for the gold tailings cyaniding, xinhai will apply the method of dry tailing stacking That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it

The thickened pulp, or tailings, will then be treated to destroy the remaining cyanide prior to the tailings leaving the processing plant The tailings will be pumped to the tailings storage facility which will consist of an engineered earth dam and a water recovery system

Hazardous Properties Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and

May 15, 2017 In addition to these potential direct financial benefits, bio processing the tailings wastes would help to remove some, at least, of the environmental hazard that these tailings represent protracted release of metals and acid into the wider environment, much in the same way that bio processing cobalt rich tailings at Kasese in Uganda

In many countries, elemental mercury is used in artisanal and small scale gold mining Mercury is mixed with gold containing materials, forming a mercury gold amalgam which is then heated, vaporizing the mercury to obtain the gold This process can be very dangerous and lead to significant mercury

Drilling undertaken in 2014 showed an average grade of 043 oz/t or 1 47g/t, supporting the development of a system to re process the tailings The initial design and testing took place over 2015 and 2016 with the first gold pour coming from the tailings re processing project in July of 2016 True North Tailings Mineral Reserves:

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra cone terrikon, are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining
