Matte Slag is composed of several different phases,
including metallic and non-metallic compounds. These
compounds are carefully controlled during the smelting and
cooling process to achieve a uniform structure with high
density.
What is "Matte Slag" (Copper Slag)? It is
one of the types of slag produced during the copper
extraction process, where impurities rise to the surface of
the molten copper and are then slowly cooled to create a
uniform and durable structure.
High Density: High density gives Matte Slag
greater ability to penetrate hard materials. This feature
allows the sandblasting process to be carried out faster and
at a lower cost.
Uniform Structure: The uniform structure of
Matte Slag means its particles are very similar in size and
physical properties. This structural integrity makes it more
precise and effective in sandblasting and abrasive blasting
processes.
After the copper slag is collected by the slag extractor, it
is evenly cooled in the open air at ambient temperature.
This non-crystalline material has identifiable phases, such
as Petedunnite (CaZnSi2O6), Pyroxene,
and Iron Aluminum Oxide (FeAl2O4).
One of the notable features of Matte Slag is that due to its
gradual cooling in the open air, the forming atoms have the
opportunity to position themselves appropriately, forming a
structure with greater strength. This increases the density
and specific gravity of Matte Slag. Furthermore, Matte Slag
has a hardness of at least 6 on the Mohs scale and meets the
international standard ISO-11127-4. It
falls under category A of the
SSPC-AB1 standard.
