Pricing has continued to slide fetching less than 4 cents per gram ( 1.13 per ounce) as of late November 2017. China plays a huge role in rare-earth elements—one that is forcing users of these metals to look for recycled sources. For instance China produces more than 90
Currently the majority of electronic waste is disposed of in a landfill.The remainder is processed in an energy inefficient manner where only small amounts of the available metals are recovered. This is a problem for a number of reasons. This waste contains recoverable trace amounts of precious metals and larger quantities of a variety of other metals and alloys especially copper

Yet with deeper understanding and the real need for resources the recovery rate is not comprehensive enough to describe the extent of recycling due to the fact that it is not capable of reflecting the required purity of the products as for some techniques the recovery rate is very high (>90 ) while the product purity is particularly low including several components with concentrations
The rapid growth in the use of electronic equipments combined with early obsolescence has contributed enormously to the generation of large quantity of electronic (e) waste. One such e-waste the mobile phone printed circuit boards (PCBs) contain various precious metals which can be extracted by different hydrometallurgical routes. The present work deals with the recovery of gold using
With the development of technologies and the change of consumer attitudes the amount of waste electrical and electronic equipment (WEEE) is increasing annually. As the core part of WEEE the waste printed circuit board (WPCB) is a dangerous waste but at the same time a rich resource for various kinds of materials. In this work various WPCB treatment methods as well as WPCB recycling
Gold 0.039 Silver 0.156 Palladium 0.009 Copper 18.448 Other metals 9.35 Non-metals 72 Gold silver copper and palladium contributed to more than 91 of the total worth of metals found in PCBs and thus these four metals were selected for further study. The total value of these metals added up to 24.3 per kg of PCB. II. METAL RECOVERY PROCESS
Physical recycling is a promising recycling method without environmental pollution and with reasonable equipment invests low energy cost and diversified potential applications of products. However separation between the metallic and non metallic fraction from waste PCBs has to be enhanced.
"We ve found a simple cheap and environmentally benign solution that extracts gold in seconds and can be recycled and reused " said Foley an
These are usually copper (which has a small amount of value) but on older or high performance boards they can ofen be gold. This circuit board has many low value bulky components but the traces are gold. This is a beautiful board with gold traces fingers and valuable IC chips. It is from a telecom board.

Pyrolysis of Printed Circuit Boards T. R. Mankhand K. K. Singh Sumit Kumar Gupta Somnath Das Department of Metallurgical Engineering Indian Institute of Technology (Banaras Hindu University) Varanasi 221005 India Abstract Printed Circuit Board (PCB) is an essential component of almost all electrical and electronic equipments. The
Put the gold fingers and clean circuit boards in the coffee pot in another container mix two parts muriatic acid and one part hydrogen peroxide and add to the coffee pot until it just covers the gold fingers and wait a week giving it a stir daily. Since I have a week I will move on to processing my solid low grade gold
Reusing and Recycling Big Challenges Big Opportunities. It takes 100 tons of gold ore to get 10 ounces of the precious metal said Privahini Bradoo CEO of BlueOak Resources a California-based
Abstract. Current research on leaching precious metals from waste printed circuit boards (PCBs) in the world is introduced. In the paper hydrometallurgical processing techniques including cyanide leaching thiourea leaching thiosulfate leaching and halide leaching of precious metals are addressed in detail.

This question arises because the gold loss cost will be the part of product cost. Compared to the other metals gold is the costliest metal which is used as an ornament. Is there any easiest method for gold recovery from various dusts without using acids and chemicals Thanx. Madhavan Employee
Gold Recovery From Surface Mount IC CHIPS Introduction Surface mount ic chips have a good quantity of gold. Gold quantity is also different in different ic chips. In this tutorial we will learn about gold recovery from ic chips (black surface mount ic chips recycling). In this tutorial only gold shall recover from ic chips.
Hydrometallurgy is a successful technique used worldwide for the recovery of precious metals (especially gold and silver) from ores concentrates and waste materials. It is generally preferred over other methods because it can offer high recovery rates at a relatively low cost.

Beginning work at Steinert’s Test Centre in Cologne Germany in May 2015 Swiss company Bühlmann Recycling prepared a demanding sorting task for the equipment company’s applications specialists. The challenge was to use a flexible facility (i.e. one that could be adapted to future input materials) to manufacture a variety of products.
Recycling and reusing electronic components could be made much easier with a new polymer that produces a circuit board that will dissolve when immersed in hot water. The circuit board was developed by the UK’s National Physical Laboratory (NPL) as part of the ReUSE (Reuseable Unzippable Sustainable Electronics) project.
