Copper Slag (CS) is a solid waste produced during the industrial smelting of copper (Gorai et al., 2003).The current pyrometallurgical copper smelting process is mainly through the Ausmet furnace (Fig. 1); the furnace slag goes through the flotation process to obtain copper matter, yielding a composition of CS corresponding to 30–40 % of Fe, …

Copper slag is a by-product of copper manufacturing that is obtained through a process called pyrometallurgy. ... This granulated slag is typically composed of small, well-defined, and angular particles, with sizes ranging from 4.75 mm to 0.075 mm (Gorai et al., 2003). The porous nature of granulated slags contributes to their lower weight.

The expanded slag ball is a porous lightweight slag formed by cooling the slag with high cooling water. The production methods include spray method, trench method and roller method. It can be used to make lightweight aggregate, inner wall panels, floors, etc. it can also be used in load-bearing structures. Blast furnace slag can also be used …

The proportions (by weight) of copper slag, added to concrete mixtures were as follows: 0% (for control mix), 20%, 40%, 50%, 60%, 80% and .The control mixture (with 0% copper slag and sand) was designed to have a target 28 days compressive strength of 45 N/mm2, using a water binder ration of 0.45.

slag sample showed that 80% of the copper slags was smaller than 40 mm. To perform the flotation tests, the copper slag samples had to be crushed to to reach appropriate size. Three crushing steps were considered including the primary jaw crusher (d 80 =28mm), secondary jaw crusher (d 80 =10.04mm) and roll crusher (d 80 =1.6mm). All

Granulated copper slag used in this study is available in the size range of 2.36 mm to 0.600 mm which is similar to crusher dust normally used as fine aggregate in hot mix asphalt (HMA). Hence, copper slag can be directly used without splitting/crushing into smaller size for its bulk utilization in the construction of bituminous …

The Small Copper is usually seen in ones and twos, but in some years large numbers may be found at good sites. Males are territorial, often choosing a piece of bare ground or a stone on which to bask and await passing females. They behave aggressively towards any passing insects, returning to the same spot when the chase is over. Though it remains a …

By referring to equipment manufacturer's bulletin on crushers, Fig. 1, a crusher producing 80% passing 3/4″ requires a close side setting of approximately 5/8″. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. The 159 indicates a 548 crusher size with 1″ eccentric throw.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

The analytical results in Table 1 show that the slags tested varied in total copper content from 5.2% to 15.1% Cu with the ndida slag having a mid-range value of 9.8% Cu. The CaO/Fe ratio was typically 0.63 except for the ndida slag where it was 0.55. In general, the higher the copper content the more oxidised the slag.

The temperature of the melting slag was about 1200 °C, and then water quenching was utilized with the cooling rate of about 100 °C/s. Afterwards, the solidified slag was smashed into small particles by a crusher. The chemical composition of slag was carried out by an X-ray fluorescence spectrometer (ARL ADVANT'X, Thermo, USA).
