There are presents the internal recycling in anode furnace, in addition to mainly blister copper and converter copper. During the process
there arise the two types of semi-finished products intended for further pyro metallurgical processing: anode copper and anode slag. The
stream of liquid blister copper enters into the anode furnace treatment, in which the losses are recovered, e.g. copper, resulting from
oxidation and reduction of sulfides, oxides and the oxidation of metallic compounds of lead, zinc and iron. In the liquid phase there are
still gaseous states, which gives the inverse relationship relating to the solid phase, wherein the gases found an outlet in waste gas or
steam. The results of chemical analysis apparently differ from each other, because crystallite placement, the matrix structure and the
presence of other phases and earth elements are not compared, which can be regained in the process of electrorefining. One should not
interpret negatively smaller proportion of copper in the alloy, since during the later part of the production more elements can be obtained,
for example from sludge, such as platinum group metals and lanthanides. According to the research the quality of blister copper, to a large
extent, present in the alloy phase to many other elements, which can be recovered.
The scope of work included the launch of the process of refining slag suspension in a gas oven using a variety of technological additives.
After the refining process (in the context of copper recovery), an assessment of the effect of selected reagents at the level of the slag
refining suspension (in terms of copper recovery). Method sieve separated from the slag waste fraction of metallic, iron - silicate and
powdery waste. Comparison of these photographs macroscopic allowed us to evaluate the most advantageous method of separating
metallic fraction from the slag. After applying the sample A (with KF2 + NaCl) we note that in some parts of the slag are still large
amounts of metallic fraction. The fraction of slag in a large majority of the elements has the same size of 1 mm, and a larger portion of the
slag, the size of which is from 2 to 6 mm. Definitely the best way is to remove the copper by means of the component B (with NaCl ) and
D (with KF2
). However, as a result of removing the copper by means of component C (with CaO) were also obtained a relatively large
number of tiny droplets of copper, which was problematic during segregation. In both cases we were able to separate the two fractions in a
fast and simple manner.
