Exotic and
Precious Metals recycling
and other assorted
Mixed Metal wastes and
Surplus
materials.
Metal Recycling Operations
Typically the Scrap Metal Recycling business is involved in identifying,
manually or mechanically sorting or segregating by
type of metal or alloy and then packaging the clean sorted commodity according to market specifications.
Alloys refer to a combination of two or more metals that have been melted together into a material known as an alloy.
Scrap recycling operations handle Directly meltable metal scrap and
metal content materials that are recovered in a
refining
process.
For tips on identifying metals and alloys browse the
Types of Metals
that interest you.
Refining & Recovery Methods
For scrap metal items that are not easily
sortable
and Directly meltable, some sort of refining or recovery method must be applied.
Metal content materials,
residues
and waste stream byproducts with a complex matrix must each be handled in a method
determined by the particular materials contained.
As a part of the
4Rs strategy
we have outlined three main types of refining and recovery.
Thermal Refining & Smelting
The
pyrometallurgical
reduction or melting of metals,
oxides,
sulphides or other metal matrix residues,
commonly referred to as smelting,
is used to drive off impurities and by using fluxing agents can consolidate the undesirable components into a slag.
The result of the smelting process is the recovery of a purified metal product typically in the form of a metal ingot or billet.
Wet Chemical Processing
The
Hydrometallurgical
method of leaching or dissolving the waste metal matrix into solution
allows for precipitation, cementation, solvent extraction and reduction.
Wet Chemical Processing typically suspends the metals in an ionic state facilitating
selective ionic exchange or further electrowinning.
Bioleaching
Bioleaching is a microbial process that utilizes microorganisms to perform bio remediation to oxidize metals.
Metal Eating Bacteria (MEB) and specialty cultured enzymes have also been harnessed or developed for use in non-traditional
applications like the recovery of gold from seawater.
Electrochemical Refining
Electrowinning
Electrowinning is a process used to recover metals from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution.
Electrowinning is commonly used to recover base metals such as copper, zinc, nickel, and cobalt.
In electrowinning, an electrical current is passed from an inert anode through a leach solution containing the dissolved metal ions
so that the metal is recovered as it is reduced and deposited in an electroplating process onto the cathode.
Electrorefining
Mixed metals are melted into a bar form which is referred to as a refinery anode
(in the gold refining industry this is commonly called a dore bar).
The refinery anode may be used as the sacrificial electrode as one half of an electrochemical cell and when an electric current
is applied to the cell the selective electrorefining of individual metals by reactivity level is preformed.
Selectively, individual metals may be plated onto the cathode in the form of a pure metal and the balance of the metals deteriorate
into to the form of a mud or slime. Wrapping a bag around the anode allows for the capture of the mud.
Electrometallurgy
ElectroRefining
Electromagentic Recovery
The electometallurgical method utilizes Electromagnetic energy for the selective recovery of purified metals
through traditional electrowinning, Electrorefining or by harnessing the evolving clean technology of electrostatic
participation,
Elemental
Solidification
and agglomeration.
Additional information about specific types of Scrap Metal Recycling is available :
Ferrous Metals
Ferrous metals refers to iron (Fe) based materials which include
all types of Iron Scrap and
Scrap Steel Recycling
Non-Ferrous Metals
Non-ferrous metals fall into 3 main groups Light Metals, Red Metal and White Metals, all of these metals are non-magnetic.
To obtain further recycling info choose the metal you are interested in :
The Light Metals group consists of
Scrap Aluminum
and
Magnesium Scrap (Mg)
The Red Metals group is made up of
Scrap Copper
and copper alloys such as
Scrap Brass
and Bronze.
White Metals is a group that includes
Lead Recycling,
Scrap
Tin
and
Scrap Zinc Recycling.

Mixed Metals Scrap Recycling
If you wish to Buy or Sell Mixed Metals Scrap, simply
ADD your inquiry
to the Inter-Continental Metal Exchange.
Several industries generate a variety of mixed metals wastes and by-products.
Since these material contain a wide mixture of material, to be recycled they fall into a class of their own.
These materials include
E-Scrap Recycling,
multiple styles and types of
Battery Scrap
and a mixture of
Metal Residues
containing a combination of metals.
The central
resource recovery
of waste materials typically involves the size reduction or shredding
and progressive separation of the different fractions contained within the waste stream.
One of the fractions recovered is a
Mix
of shredded Non~Ferrous Metals.
These mixed metal shreds require further separation into the marketable grades of each of the individual metals.
Dismantling of Liberated
Electronic Components,
Mixed Components (sheared or dismantled) may provide the opportunity to produce
Granulated Residue Nuggets
or a
Synthetic Ore
containing a mixed matrix of metals complexes.
In addition to the recovery of base metals a comprehensive approach may be one method to recover
individual elements of selective groupings of
Precious Metals
and strategic
Critical Materials
including
Rare Earths.
The
selective
extraction of any predominate items results in the concentration of the balance of the materials
which allows for the sequential recovery of
Trace
Elements and/or
Residual
Waste Materials.
This is a broad spectrum approach that encompasses the maximum range of recovery potential for any concentration of common and
Exotic Metals.
Surplus Metals Inventory
If you wish to Buy or Sell new metals or metal products that are obsolete, end of line or liquidations,
Please feel free to ADD your inquiry to the
Surplus Metals Inventory
exchange.
The exchange service connects distressed excess and over stocked metal inventory sellers directly with
ready buyers.
Secondary Commodity Prices
There are a number of Scrap Metal Price
reports
available that span the spectrum of scrap grades and specifications by individual commodity.
These reports reflect current
daily spot market,
multi-year price summaries,
historic prices, and
market price trends.
The Scrap Metals Composite Index
The Scrap Metals Composite Index tracks the daily
changing market
prices in the scrap metals industry.
The Index consists of a weighted basket of nine (9)
benchmark grades
of scrap metal and the Index includes snapshots of 5 viewpoints of market trends : the past 7 days,
past 30 days, past 90 days, past 1 year and past 2 years.
