The best example of a safe and effective waste management program is that of the Żelazny Most tailings pond in Lower Silesia, Poland. This is the only site for storing floatation waste coming from all of the mines in the Polish Copper Belt. At the same time, it is the most important link in the copper concentrate production process.

copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].

The results show that the electrical resistivity of iron ore mine tailings produced in Western. Australia in dry condition ranges from 11 kΩm in a more dense state to 19 kΩm in a very. loose state, while that in fully saturated condition ranges from 20 Ωm for a very dense state to. 31 Ωm in a very loose state.

Froth flotation circuit design and basic testwork requirements. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineralladen froth. The remaining unfloated mineral slurry will be discharged as tailings.

SkimAir is designed for flotation in the grinding circuit to process cyclone underflow where heavy minerals concentrate. The SkimAir unit improves metallurgical performance while providing a more stable feed to the conventional flotation circuit and improving dewatering with coarser final concentrate.

The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings. The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more than 20%, and the concentration ...

of oxide minerals. Advances in flotation reagents can make the recovery of oxides by flotation a more effective and economic process. Grinding and surface chemistry are critical to the success of oxide flotation. Overgrinding of the brittle minerals is avoided by stage grinding and careful selection of equipment.

some cases multiple tailings ponds were developed on a single mine site. The size of tailings ponds in the copper sector appeared to be significantly larger than average. The site visits also noted that most tailings ponds used some form of barrier on the bottom and sides of tailings ponds to retard flow of water through the bottom.

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and "worthless" rock, called gangue (pronounced "gang"). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called "collectors" are added to the slurry and bind to the copper particles, making them .

General observations regarding vegetation success on reclaimed copper tailings in the southwestern United States are as follows. Organic amendments can be successfully used to reclaim circumneutral tailings, however, low to moderate amendment rates should be used to limit highnutrient conditions that favor for undesirable nonnative species.
