Metal Content Residues
Please feel free to Add your Buy or Sell inquiry to the Exotic Scrap Metals Exchange.
The exchange service connects generators of metal content by-products with dealers, processors and refiners
interested in recovering metal values from
complex waste
materials.
Concentration & Selective Extraction
The methods of residue recovery typically rely on the
Concentration & Selective Extraction
of one specific item at a time.
Once the first selected item is removed, a new target is selected and the
cycle
is repeated
until all the trace elements have been recovered.
The overall efficiency of this process may be improved by consolidating fresh inputs of "like" materials at each stage.
Metal Content Residues
Metal content residues include waste,
by products, sludges, filtered materials, sweepings, powders, plasma dust, grit, spent catalysts, blast media,
fluxing materials and dust collector residues.
Electronics scrap processing by-products and End of Life - end of the line rejects.
Residue Generation Trends
Modern manufacturing techniques of digital age products generate End of Life (EOL) waste streams containing
complex multi-layer composite materials with
trace
metallic elements and inert inorganic substraits.
The evolution of advanced electronics, sensors and displays utilize a huge assortment and types of
Strategic
Rare & Precious metals.
Many specialty technologies require only trace amounts of metals,
processes such as thin film coating and sputtering deposit minute quantities of exotic metals
that are impossible to manually segregate.
This proliferation of exotic trace elements demands a revised approach to
Residual Materials Management.
Residual Materials Management
To aline with environmental sustainability practices of today a new or expanded strategy to
the approach and treatment of residual End of Life (EOL) materials
is necessary to prevent the release of potentially toxic elements into the atmosphere
and to allow for the recovery of valuable strategic finite resources.
The recovery of any type of trace elements commonly relies upon a multi-stage process of concentration and selective extraction.
Residual Consolidation
By consolidating residues with a
similar matrix
together (referred to as Like Materials)
you can target your recovery efforts on specific elements on a priority or sequential basis.
Typically you would choose or prioritize elements with the most abundant concentration in your matrix.
By targeting and recovering the primary elements you reduce the total volume of the remaining left over materials,
this secondary generation residual material will have a newly calculated matrix or different mix and concentration of elements.
This method amplifies the concentration of all the remaining elements which then allows you to repeat the process perpetually,
ultimately
recovering
all the elements.
In the past we compressed the like materials into uniform shapes for ease of handling, storage and sampling.
We referred to this agglomeration process as
Cannon Balling.
We accumulated different groupings of Cannon Balls based on similar matrix of the elements contained.
Once we accumulated sufficient quantity of
Like Cannon Balls
we would proceed to
Refine & Recover
the next sequence or generation of residuals.
A balanced or accordion approach to
Refining & Recovery
provides multiple options of Pyrometallurgical, Hydrometallurgical, Electometallurgical or other methods
and allows flexibility to respond to current market conditions.
Residue Feedstock
An example of a Residual Materials Management feed stock is
the production of synthetic ore containing Strategic Rare Precious Residues in the form of
Granulated Residue Nuggets
generated from a specific mixed waste stream.
Synthetic Ore
With the
proliferation
of complex multi-layer composite materials with trace metallic elements,
the management of residuals transitions from a fringe activity
into the mainstream production of synthetic ore.

To meet environmental sustainability goals the comprehensive treatment of residual End of Life (EOL) materials is
a solution to prevent the release of potentially toxic elements into the atmosphere
and to allow for the recovery of valuable strategic finite resources.
Heavy Metal Concentrates
The typical method of treatment of heavy metal content in sludges and wastewater is to dilute or reduce the ppm content to a
discharge compliant level. This approach does not eliminate the release of
potentially toxic or hazardous heavy metals that may eventually accumulate in the environment.
The alternative approach is the removal of the non-metal fractions resulting in concentrating the balance of the materials
into an enriched ore as a feed stock for the recovery of Strategic Rare Precious heavy metal
Residues.
