Use of recycled copper slag for blended cements de Rojas

Jan 28, 2008· Copper slag is a by‐product generated during smelting to extract copper metal from the ore. The copper slag obtained may exhibit pozzolanic activity and may therefore be used in the manufacture of addition‐containing cements. In this paper the effect of the incorporation of the copper slag in cement is measured.

Utilization of copper slag in cement and concrete

Aug 01, 2008· The physical properties of copper slag are given in Table 2.As seen, the density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3 that means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.

Validating the Use of Slag Binder with 91 Percent Blast

The use of ground granulated blast furnace slag (GGBFS) is environmentally sustainable and prevalent in the cement industry, but the original alkali-activated slag binder cannot be used for mine backfilling. Few reports have studied slag binders with high slag proportions (>90%) and low-cost activators (solid waste is used) that have higher performance than cement for backfilling.

Copper Launders TENOVA

Water-cooled copper launders use the freeze lining principle to reduce component wear. Lower wear means longer launder life, cutting long-term maintenance costs and downtime production losses. Many launder designs present an inherent safety risk by positioning the water cooling passages underneath the slag

slag from copper mines pizzeriegulliver.cz

Slag from Ancient Copper Mines Shows that the Earth's. 15-12-2010· The Earth's magnetic field fluctuates in intensity. But until recently, most scientists thought that it wouldn't change more than 16% in a century. Slag recovered from a 3,000-year old Egyptian copper mine indicates that the magnetic field could double in just 20 years.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Optimization of copper slag waste content in blended

copper slag (C). From the Figure 1, we find that the mixing line intersects the pozzolanic boundary line at point (O) where the ratio value is 20.1 %. This value is con-sidered to be the theoretical optimum value of copper slag in the blended cement with zero content of calcium hydroxide. This optimum value is

COPPER SLAG IN CONCRETE AS REPLACEMENT MATERIAL

copper slag is generated as a waste (Gorai et al., 2003). Around 24.6 million tons of Copper slag is generated from the world copper industry (Gorai et al 2003). Though some portion of copper slag is widely used in the sand blasting and in the manufacturing of abrasive tools, the remainder is disposed of without any further reuse or

Mechanical Activation of Granulated Copper Slag and Its

Mechanical activation of granulated copper slag (GCS) is carried out in the present study for the purposes of enhancing pozzolanic activity for the GCS. A vibration mill mills the GCS for 1, 2, and 3 h to produce samples with specific surface area of 0.67, 1.03 and 1.37 m2/g, respectively. The samples are used to replace 30% cement (PC) to get 3 PC-GCS binders.

What is a Copper Slag? (with pictures) wiseGEEK

Jan 28, 2021· Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
