NEW Precious Metal Recovery from E-Waste & I-Waste

What is E-Waste

Waste1E-waste for short – or Waste Electrical and Electronic Equipment (WEEE) – is the term used to describe old, end-of-life or discarded electrical appliances. In this catalogue, “e-waste” is used as a generic term embracing all types of waste that consists of electrically powered components containing Precious Metals (PM) or Base Metals (BM). E-Waste contains both valuable materials (PM and BM) as well as hazardous materials which require special handling and recycling methods. Some examples :
  • Information and comunication equipment
  • Entertainment and consumer electronics
  • Medical Instruments and equipment
 

What is I-Waste

i-Waste – or Industrial Waste – is a term used to describe those materials produced with various industrial manufacturing process that , as with e-Waste, contain Precious Metals (PM) or Base Metals (BM) . Some examples are :
  • Luxury & artistic goods
  • Automotive industry (i.e. catalysts)
  • Oil and petroleum industry (HCR and CCR)

WHY RECYCLE e-WASTE & i-WASTE?

Electronic appliances and industrial products are composed of hundreds of different materials that can be both toxic but also of high economic value. While bulk materials such as iron, aluminium, plastics and glass account for over 80 weight %, valuable materials are found in smaller quantities but are still of high importance. Gold, silver, copper, platinum etc. are just some of the valuable substances which turn recycling of e-waste and i-waste into a lucrative business opportunity.

e-WASTE &i-WASTE RECYCLING PROCESSES

The selection of the recycling process depends on three main factors :
  • Type of material and its complexity
  • Metal Content
  • Volume

5CLASSIFICATION The initial step in the recycling and recovery process is to classfiy, evaluate and separate the type of material according to metal content and recoverability.     6ENRICHMENT The next step in the recycling process is the removal of critical components from the e-waste in order to avoid dilution of and / or contamination with toxic substances during the downstream processes.       MECHANICAL PROCESSING Mechanical processing is the next step in e-waste treatment, normally an industrial large scale operation to obtain concentrates of recyclable materials in a dedicated fraction and also to further separate hazardous materials. Typical components of a mechanical processing plant are crushing units, shredders, magnetic- and eddy-current- and airseparators. The gas emissions are filtered and effluents are treated to minimize environmental impact.

6-1 CHEMICAL STRIPPING The chemical stripping of precious metals from e-waste or i-waste material normally requires acids, usually cyanide. The secure handling of these substances is extremely critical – Italimpianti Orafi has therefore designed units to reduce all environmental and safety hazards to a minimum, including cyanide neutralisation and treatment installations. Chemical stripping agents work on the surface of the material being treated and basically strip the metal surface content into solution. Embedded metals e.g. in components or interboard layers are not reached unless the material is finely milled.       6-1REFINING The subsequent step of e-waste recycling is refining. Refining of resources in e-waste is possible and technical solutions exist to get back raw with minimal environmental impact. Most of the fractions need to be refined or conditioned in order to be sold as secondary raw materials.       6-1 INCINERATION Incineration is the process of destroying waste through burning. Because of the variety of substances found in e-waste, incineration can be associated with a major risk of generating and dispersing contaminants and toxic substances. The gases released during the burning and the residue ash are often toxic. In view of this, Italimpianti Orafi designs incineration plants to specifically avoid risks to the environment by incorporating state-of-the-art technologies for real-time process analysis and automatic fume treatment, thus meeting EP requirements as stated by the majority of EPA regulators worldwide.   MILLING OPERATION The milling operations are a step in the recycle process, subsequent to the incineration process, in which the resulting materials are crushed to a fine powder. 6-1 SMELTING The smelting process is used to separate precious metals (PM) and base metals (BM) from inert material residues from the incineration process. High temperature melting furnaces are used in conjuction with special melting fondents. 6-1 LEACHING Leaching operations are very similar to chemical stripping, as previously mentioned. Leaching agents work on the surface of the material being treated and basically strip the metal surface content into solution. Embedded metals e.g. in components or inter-board layers are not reached unless the material is finely milled. 6-1

COST ANALYSIS

There are several key factors used to analysis the cost effectiveness of recycling e-waste and i-waste materials :
  • Initial contents of precious metals
  • Local manpower costs
  • Electricity costs
  • Chemicals
  • PM recovery rate and efficiency
  • Equipment investment costs
  • Other costs like transportation, warehousing, Marketing, Sampling etc.
