· Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.
The treated spent copper slag can be recovered and put to good use as replacement of sand in concrete. For structural aspect, the use of copper slag as a partial alternative of sand in concrete allows for up to 10% by mass. Technology and process will involve the treatment and reconstitution of the spent copper slag to satisfy all the ...

This cooling process fractures the slag into coarse and angular particles, making it an ideal abrasive blasting slag with optimal blasting properties. OMGRIT Copper Slag is approved by the major shipyards, oil gas companies, paint manufacturers, coating contractors, tank builders, pressure vessel fabriors, offshore yards and construction chemical manufacturers.
Slag cleaning can enhance the recovery of valuable metals in existing pyrometallurgical processes, or can produce economic value from recycling old slag dumps. For example, a process has been developed and implemented industrially for recovering cobalt from copper smelting slag in a .

By adopting this multifurnace system, smelting, slag cleaning, and ...
· Copper slag has a specific gravity of which is higher than that for sand () and OPC () which may results in production of HPC with higher density when used as sand substitution. Also, the measured water absorption for copper slag was % compared with % for sand.
· LifeCycle Assessment of HighStrength Concrete Mixtures with Copper Slag as Sand Replacement. Aysegul Petek Gursel 1 and Claudia Ostertag1. 1Department of Civil and Environmental Engineering, University of California, Berkeley, CA 94720, USA. Academic Editor: Ghassan Chehab. Received 16 Apr 2018.
this page is provide professional process of making construction sand from copper slag gulin provide the copper slag as additive in cement making .The Slag Cement Association provides industry tools, resources and information on slag cement copper slag be used for slag cement.
· This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were plastered. The studies showed that .
· Copper slag is one of the possible abrasives that can be used. Other blasting media that can be considered are sand, glass, plastic or water. Blasting with copper slag is generally done for two different purposes. First of all, copper slag blasting is an effective way to remove mill scale, rust
· A method of making concrete from base metal smelter slag includes grinding the slag to a size within the range of from about 250 to about 425 mesh to produce ground slag cement, mixing the ground slag cement with Type 3 high early strength Portland cement in a ratio of at least about :1 by weight, and adding sand and stone to produce a concrete.

· The processes used for Gold Refining are as follows: ... zinc and copper an equal weight of sand, ... and if all the copper is removed into the slag, from 10 to 50 per cent, of its weight of silver is also oxidised, and passes into the slag, from which it is recovered by fusion with carbon and iron.
This paper reviews the use of industrial waste material From copper smelting process, copper slag is produced as a 'copper slag' in the construction work as a replacement of byproduct. Per unit production of copper, approximately cement, sand and aggregate to reduce the cost of ton of copper slag is generated as a byproduct.
