The issue of E-waste disposal is concerning all the stakeholders from policymakers to the end users which have accelerated the research and development on environmentally sound disposal of E-waste. The recovery of metals (gold tantalum copper iron etc.) from E-waste has become an important focus. The mechanical recycling thermo-chemical processes like pyrolysis pyro- hydro-
General Electronic waste is a very heterogeneous recycling material. Purchase prices are determined by the contained metals. The gold silver palladium and copper content being different between the several components circuit boards and chips we define sorting criteria for the different price groups of electronic waste in order to be able to calculate fair purchase values.
But electronic devices also comprise toxic heavy metals like lead mercury cadmium and beryllium polluting PVC plastic and hazardous chemicals such as brominated flame retardants which can harm human health and the environment.. In 2016 the estimated value of recoverable materials in global e-waste was 64.6 billion but only 20 percent of it was properly recycled to enable recovery of

Welcome. It is estimated that around 80 000 tons of electronic waste is generated in South Africa per year. For every million cell phones that are recycled 16 tons of copper 350 kg of silver 195 kg of gold and 15 kg of palladium can be recovered yet only 12 5 of all electronic waste is currently recycled. used equipment for sale crusher for municipal solid waste from gold manufactory used
As a matter of fact a ton of computer circuit board and micro chips contains as much as 800 times more gold than what is obtainable in one ton of gold. The good thing about this process is that it would only cost you about 20 US Dollars to recover 1oz. worth of scrap gold and the value of this can be as high as 300 US Dollars.

Printed Circuit Board Recycling Methods 1. Introduction to Printed Circuit Boards The Printed Circuit Board (PCB1) manufacturing process is very complicated involving many special chemicals and valuable materials. These materials discharge into the environment in the forms of wastewater spent solution and solid waste.
Since gold requires stronger chemicals to be dissolved the nitric acid will melt all the plastic and metal parts of the circuit board without harming the gold bits. Drain the nitric acid from the mixture. Use a filter to separate the solid parts from the liquid. Pick out the unmelted parts.
