WE IMPORT
We are the importer of following materials and remain in search of
finding the suppliers who could enter into long lasting agreement to
supply the materials copiously and incessantly :
Battery Plate Scrap
Specify whether automotive, industrial or mixed. Also whether they
are groups or loose. The only other metallic that might be included
could be Lead Connectors. To be free of non-metallic, i.e., plastic
or rubber, with the exception that separators may be included.
Material to be dry. May be bought on an assay basis or a flat price.
Submarine plates subject to negotiation. Review packaging
specifications and regulatory status pertaining to shipping with
buyer prior to sale.
Lead Scrap
Shall consist of clean soft scrap Lead, free of other materials such
as Lead drosse, battery plates, lead covered cable, hard lead,
collapsible tubes, foil, type metals, aluminum, zinc, iron and brass
fittings, dirty chemical lead and radioactive materials. Review
packaging specifications and regulatory status pertaining to
shipping with buyer prior to sale.
Lead Ash
Should be clean and reasonably free of other materials such as iron,
dirt, harmful chemicals or other metals. To be free of radioactive
materials, aluminum and zinc. May be bought on an assay basis or as
agreed to by buyer and seller. Other metals present such as
antimony, tin, etc., to be accounted for as agreed between buyer and
seller. Material to be readily dumped from drums. An extra charge
may be assessed if material has to be mechanically removed. Review
packaging specification and regulatory status pertaining to shipping
with buyer prior to sale.
Dry Battery Scrap
To be free of any liquid. Cases to be either plastic or rubber and
be complete including caps. Non-lead (ni-cad, ni-fe, carbonaire,
etc.) not acceptable. Industrial steel cased, aircraft (aluminum
cased) and partial, cracked or broken batteries and batteries
without caps subject to special agreement. Review packaging
specifications and regulatory status pertaining to shipping with
buyer prior to sale.
Lead Ore
Any of several minerals from which Lead is extracted. The primary
ore is galena or Lead sulphite PbS. This is unstable, and on
prolonged exposure to the atmosphere it oxidizes into the minerals
cerussite PbCO3 and anglesite PbSO4. Lead ores are usually
associated with other metals, particularly silver which can be mined
at the same time – and zinc, which can cause problems during
smelting.
The Sulfide Mineral, Galena, a Lead sulfide, PbS, is the most
important ore mineral of Lead. It can contain 86% Lead. Its
metallic, Lead-gray cubic crystals (isometric system) and cubic,
perfectly cleavable masses are distinctive and characteristic.
Hardness is 2.5, streak Lead gray, and specific gravity 7.4-7.6.
Galena is a widespread mineral deposited by hydrothermal solutions
as large, irregular masses in dolomitize limestone and in zones of
contact metamorphism and as veins in volcanic rocks. It often
contains enough silver to be mined as a silver ore.
Most commercial deposits of Lead ore are in the form of veins, where
hot fluids have leached the ore from cooling igneous masses and
deposited it in cracks in the surrounding country rock, and in
thermal metamorphic zones, where the heat of igneous intrusions has
altered the minerals of surrounding rocks. Lead is mined in over 40
countries, but half of the world's output comes from the USA,
Canada, Russia, Kazakhstan, Uzbekistan, Canada, and Australia.
Lead Concentrate
Ore is recovered by blasting then dumping, followed by crushing and
finally hoisting to the surface for treatment. In mining, the ore is
extracted by drilling or blasting and then crushed and ground. The
ore is then treated using extractive metallurgy. The Froth flotation
process separates the Lead and other minerals from the waste rock
(tailings) to form a concentrate. The concentrate, which can range
from 50% to 60% Lead, is dried and then treated using pyrometallurgy.
The concentrate is sintered before being smelted in to produce a 97%
Lead concentrate. The Lead is then cooled in stages which causes the
lighter impurites (dross) to rise to the surface where they can be
removed. The molten Lead bullion is then refined by additional
smelting with air being passed over the Lead to form a slag layer
containing any remaining impurities and producing 99.9% pure Lead. |
