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.

BENEFIT OF ITALIMPIANTI ORAFI TECHNOLOGY

  1. Italimpianti Orafi is able to provide a turn-key close loop process which includes recovery and refining of all precious metals like gold, silver, platinum and palladium (including rhodium & ruthenium)
  • Italimpianti studies the products’ metallurgy and can customize the recovery process to suit to clients’ needs
  • Italimpianti Orafi is able to committ to the close loop environmental process which can comply with WEEE, EPA or any other international regulations
  • Best Available Chemical Technquies
  • Close Loop Process
  • Comply with all environmental regulations
  • High performance and better returns
  • Transparent and 100% accountable
  • Enviornmental friendly etc.
GOLD/Italimpianti are able to supply a wide new range of turn-key plants, above and beyond our standard units, for the chemical or electrolytic treatment of gold, silver and PGM metals. These plants can be fitted with the necessary instruments for the depuration of gas, liquid and solid effluents within the limits dictated by environmental laws and regulations, as well as state-of-the-art systems to recover precious metals present in waste material up to the trace level.

GOLD/Italimpianti can also supply generic and detailed engineering services, on-site technical assistance and know-how transfer.

I hope this information will help you during the evaluation and choice for your precious metals treatment equipment requirements. Moreover we can provide you with many other service plants such as chillers, cooling towers, demineralisation and decalcification plants etc.

E & I WASTE: In order to prepare and issue a preliminary offer we need to understand the size and scope of the project you intend to set up. Unlike many other areas in which we work, E-WASTE projects require an substantial amount of detailed information before an offer can be made, which involves analysing actual samples of the material to be treated.

The ideal next step would be for your company to send us :

- A detailed list of e-waste materials you intend to treat (PCBs, PCs, Mobiles, x-ray films etc.)

- Intended quantities on a monthly basis

- A government certified Assay report for each material clearly stating the composition and metal contents. If this isn’t possible, we require you to send us a 10-20 kg sample of each material so we can carry out the necessary tests.There will be a cost for these tests.

- Final refining purities for each metal you want to refine

- Final required shape/form of the refined metal.

Because metal contents vary widely depending on the type of material, the ideal treatment method can also vary substantially depending on which metals are present, their concentration & which ones you want to recover.

While the cost of such a setup would vary between Euro 2,000,00.00 and 3,000,000.00, I do wish to point out that in order to properly prepare an offer suited to your exact requirements we would recommend organising a meeting in Arezzo, Italy with our technical teams where we can discuss the project in greater detail and fine tune the equipment accordingly.

If you will not be requiring the mechanical treatment part, please consider an approximate cost of Euro 800,000.00 to Euro 1,000,000.00 for the refining equipment only.
