Slag, copper refining is defined as :
Substance produced at high temperature in a liquid state, by
melting mixtures of metal oxides and non-ferrous metals (from
primary sources such as copper ores, matte, or anodes) or by
oxidizing metals (from copper rich materials such as metals,
alloys or metal oxides).
Slag from copper refining contains relatively high amounts of
copper oxides or sulphides, and various amounts of other
non-ferrous metals oxides
- In any copper
smelter large quantities of copper slag are discarded as waste
material causing space and environmental problems. This
discarded slag contains important amounts of metallic values
such as copper and iron
- Currently
copper slag is mainly applied as a building material
- It has been
estimated that for each ton of copper produced about 2.2 tons of
slag are generated.
- These slags
contain about 0.7–2.1% Cu and are discarded as a waste product.
Today the demand is such that even discarded slag with about 1%
Cu is considered to be a valuable resource
- Various
characterization studies undertaken for the copper slag indicate
that it mainly consisted of silica and iron oxides with traces
of sulphides
- Copper slag
contains highly toxic lements like arsenic, barium, cadmium,
copper, lead and zinc
- The disposal of
copper slag is one of the major issues for environmentalists as
dumping of copper slag as a waste material may cause severe
environmental problems
-
Copper mining capacity is estimated to reach
27.5 million tonnes copper in 2017
- A super slowly
cooling could be the solution to treat smelting copper slag in
order to recover copper and silver into the produce matte and
generate a remaining slag with large crystal size of magnetite
that allow to release molybdenum
- The high Fe
content in the copper smelting slag can be used as a high-value
element that can replace the foundry pig iron.
