Gold Recovery 8 Steps (with Pictures)Instructables
The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery
Status of electronic waste recycling techniques a review
· The increasing use of electrical and electronic equipment leads to a huge generation of electronic waste (e-waste). It is the fastest growing waste stream in the world. Almost all electrical and electronic equipment contain printed circuit boards as an essential part. Improper handling of these electronic wastes could bring serious risk to human health and the environment.
Managing waste in emerging markets McKinsey
· Economic growth in emerging economies is bringing prosperity, rising living standards, and overdue relief from poverty, but increased consumption typically increases resource use—especially the use of plastics—and waste production. As Exhibit 1 illustrates, the rapid surge in waste volumes since 2007 is straining waste-management systems in many developing countries, with negative effects
Recycling Method Of Crosslinked Polyethylene
· XLPE is widely used in wire and cable coating layer, motors, transformers and other high voltage resistance, high frequency of heat-insulating material, heat-shrinkable film and tube, all kinds of pipe (such as hot water pipes ), corrosion-resistant components of chemical production equipment, containers, foam and other fields with its superior performance.
Importance of Recycling E-Waste. Dispose of E-Waste Wisely
· One of the benefits of recycling e-waste is being able to extract and reuse these precious metals. According to the United Nations, the precious metal deposits found in E-waste are around 40 to 50 times richer than that of ore that is extracted from mines 5. In fact, a tonne of E-Waste contains 100 times more gold than a tonne of gold ore.

· In electronics industry, gold and silver are used as contacts, bonding wires and switches, while palladium is used in computer hard disk drives (Diaz et al., 2016).The content of main PMs in typical electronics is shown in Table 1 (Zhang et al., 2017).In 2015, global demand for gold, silver and palladium in the field of electronics were 254 tonnes, 12,816 tonnes and 40.18 tonnes, respectively ().
E-waste recycling in Africa risks and opportunities
· Until recently, South Africa did not recognize e-waste as a threatening waste stream. According to the Department of Environmental Affairs in 2015, e-waste made up between 5% and 8% of the municipal solid waste in South Africa and is expected to grow at an alarming rate over the coming years . This has prompted government and other supporting institutions to develop e-waste management systems with a focus not only on waste disposal but also on waste reduction, waste reuse, recycling
