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.

Keywords: Copper slag, strength properties, Replace soil and sand with alternate materials _____ I. INTRODUCTION "With increasing scarcity of river sand, soil and natural aggregates across the country, there is a need to replace soil and ...
Utilization of Soil Stabilization with Cement and Copper Slag as Subgrade Materials in Road Embankment Construction Jaber Shahiri1, Mojtaba Ghasemi2,* Received: 29. 08. 2016 Accepted: 02. 05. 2017 Abstract In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag
Separating copper and arsenic has always been a major problem in the copper slag flotation process, which influences copper slag utilization and the environmental safety. A comparative study of flash smelting furnace (FSF) slag and its flotation products (concentrate and tailing) reveals the factors affecting the separation of copper and arsenic in the beneficiation process from the ...
The utilization of copper slag in concrete provides additional environmental as well as technical benefits for all related industries. Replacement of copper slag in fine aggregates reduces the cost of making concrete. Replacement of copper slag increases the self weight of concrete specimens to the maximum of 15 to 25%.
Granulated copper slag is more porous and therefore, has particle size equal to that of coarse sand. The central pollution control board (CPCB) has recommended usage of copper slag …
Abstract:The latest research results in comprehensive utilization of copper slag in recent years were systematically summarized, including extraction of valuable metals, preparation of high value-added copper slag alloys, co-processing of copper slag to prepare building materials, and application of copper slag in environmental protection and progress of other fields.
