Mineral Recovery & Refining
The recovery & refining process of wastestreams and resiudes involves the selective
consentration and extraction of indevidual minerals
by converting or crystalization into high quality specified commodities and products.
The selective order of the mineral mill process flow is based on
mineral clusters or types of minerals typicaly found together.
Industrial Mineral Recovery
Recycling
Minerals
to recover
value
from industrial and consumer products is quite a common practice,
one of the most familiar items recycled is
Waste Glass.
Some other materials that are recycled in huge volumes every day include
Asphalt or Tar based materials
and
Aggregates
(brick, block, stone, etc.)
Some other minerals include
Carbon or Graphite,
Gypsum and Drywall,
Calcium or Lime,
Salt,
Silicon,
Abrasives &
Refractories,
Desiccants,
Sulphur Recovery,
Lithium,
Water
and
Surplus Minerals
....
other Minerals
Metal Residues
The left over residues after the salt recovery process contain a variety of interesting materials
that possess some exciting potentials for the extraction of
Potassium, Magnesium and Calcium
Mineral Salts.
In addition
trace elements
containing
Base Metals,
Precious
and
Minor Metals
may be recovered.
Of particular interest are the strategic materials such as
Lithium, Manganese, Indium, Gallium, Molybdenum, Vanadium, and Rare Earth Elements
(REE),
Scrap Aggregate Recycling
Recovered Aggregate materials may be used as direct sand and gravel substitutes.
If you wish to recycle scrap brick, block, stone or recovered aggregates, simply
ADD your inquiry
to the online Minerals Recycling Exchange.
Aggregates (brick, block, stone, etc.) may be recycled from Construction and Demolition
(C & D)
Waste.
Circular Aggregate Materials
There are many opportunities to convert byproduct wastestreams into construction or building materials,
even if those materials started their first life cycle totally unrelated to the aggregates industry.
Mineral based
aggregate
material may be manufactured from a wide variety of recovered byproducts
that meet quality
specifications
suitable for use in the building and construction industry.
Mineralized CO2
and
Incinerator Ash
is an examples of byproducts that may be converted into a raw feedstock for the building and construction industry.
Aggregate Materials may also be sourced from recovered
Glass Aggregates
and Blast Furnace Slags
(BFS)
Recycled Concrete Aggregates (RCA)
Recycled Concrete Aggregates (RCA) may be derived from crushing steel reinforced concrete
removing the
steel rebar scrap
and recovering clean, sized
RCA.
Asphalt Recycling
Asphalt Recycling from road pavement resurfacing represents huge volumes of endlessly recycled materials.
If you wish to recycle
Asphalt
ADD your inquiry to the Mineral Recycling Exchange.
The online exchange service has been successfully matching generators of Asphalt wastes directly with
dealers, traders and processors of scrap Asphalt.
Large road reconstruction projects have the option of using inplace recycling equipment to regenerate and resurface
a highway, The portable systems grind and recover old road asphalt, hot regenerate and lay fresh pavement.
The use of recycled materials in the production of fresh asphalt pavement is not limited to old
asphalt from roads but may be expanded to include recovered
Glass Aggregates
and recovered old roofing materials.
The heavy Bitumen
fraction
recovered from mixed
plastics wastes
may be used as a tar additive
in the asphalt mix.
Roofing Recycling
Recycling of
Roofing Shingle Scrap,
Tar & Pitch and flat roofing tar scraps.
Once the
nails
are removed from scrap roofing the recovered material becomes a feedstock that may be
blended into the hot asphalt mix.
Tar Recycling
Tar Recycling includes Pitch and
Coal Tar Scrap,
Tar Pot Scraps, tank bottoms and cleanouts of Bitumen based products.
Lime & Calcium Recycling
If you wish to Buy or Sell recovered Lime or Calcium, simply
ADD your inquiry
to the Gems, Rocks & Minerals Exchange.
The exchange service has been successfully matching interested parties on-line since 1995.
This group of materials includes carbonate minerals such as calcite or calcium carbonate (CaCO3)
and may include materials collected from
CO2
recovery programs.
Limestone Recovery
Limestone based
Blast Furnace Slags (BFS)
are produced in the
steel making
process and contain residuals including limestone.
In addition to
aggregates,
BFS is also used in the production of mineral wools which is a component in
insulation products
and blended with
Cement Clinker.
Calcium Recovery
Shell Residue Wastes
such as egg shells, snail shells, seashells such as clam & Oyster shells
may be processed into
Recovered Calcium Powders
(Calcium carbonate CaCO3).
Recovered Calcium ByProducts may be used in
Animal Feed Supplements or as
Soil Amendment Products
and
Cement Kiln
feedstocks.
Powdered Lime is used as a feedstock in whitewash slurry.
Typically Ground calcium carbonate (GCC) CaCO3 is the preferred filler in Carpet Backing.
In the
carpet recycling
process Liberated
Carpet Backing Powder
may be recovered.
Other calcium related materials such as
Calcium Chloride
found in ice melt residues,
Gypsum
Calcium Sulfate (CaSO) and
Clay
Recovery.
Mineral Salts
The
recovery
of Mineral Salts typicaly involes the consentration, segragation and extraction of indavidual minerals
from the mixed matrix clusters commonly found in brackish wastestreams,
brines,
Cryolites,
brines
concentrates and salt cake residues.
The most common items that typicly represent the largest content of the volume of salts are
Sodium Chloride
(NaCl),
Magnesium
Salts and
Calcium
(CaCO3).
Their is current excitment and interest in the potential of developing
Lithium
as a strategic resourcefor the electronics and battery industry.
One pathway for Mineral Salts Recovery benifits from the yeild of
Exothermic Element
Energy Extraction.
Salt Recovery
If you wish to Buy or Sell Recovered Salt, Sodium Chloride (NaCl), simply
ADD your inquiry
to the Gems, Rocks & Minerals Exchange.
The exchange service has been successfully matching interested parties on-line since 1995.
If you are interested in Salt Recovery, please check-out the reclamation of
Desalination
concentrates and
brine
solutions.
One salt recovery method is the use of
Electrolysis
of Brine to produce selective resources.
There are multiple sources of Salt available for recovery, Salt Residues, Cryolites, Salt Cakes and brines.
The Aluminum
Dross
Recovery process generates a salt by-product typicaly in the form of a Salt Cake.
Silicon Recycling
If you are seeking to recycle silicon scrap, waste or by-products,
you may submit an inquiry to the
Silicon Recycling
Exchange.
The exchange service has been successfully matching producers of silicon content wastes
with users of scrap silicon materials on-line since 1995.
Silica Gel Desiccants -
Silicon Wafer Scrap -
Aluminum Silicates
Additional information regarding
Silicon Recovery
Spent Zeolites
Spent natural or synthetic Zeolite Materials, including
ceramics
and Silicates generated from filtration mediums,
semi permeable membranes and catalysts.
The term Zeolite typicaly refers to a family of several microporous, crystalline
aluminosilicate
materials.
A wide use of Zeolite materials is as an
Ionic Exchange
resin in common water softners.
Recovered
Zeolites
may be beneficial in the efforts to De-Carbonize the energy infrastructure.
Silica Gel Desiccants
If you are looking to reclaim Silica Gel Desiccants in bulk or in pillow packs, simply
ADD your inquiry
to the Desiccant Recovery Exchange.
