Leaching of copper slags in sulphuric acid and alkaline glycine media
Frontiers in Chemical EngineeringCopper slag is industrial waste, having fayalite and magnetite as main phases, copper is present in the form of chalcopyrite and chalcosine. However, the complex structure of the slag makes the dissolution process difficult, which is why methods have ...

Chloride binding of alkali-activated slag/fly ash cements
, 2019 In this study, the effects of slag/fly ash ratio, Na2O concentration, silicate modulus of activators and water/binder ratio on chloride binding of alkali-activated slag/fly ash cements (AACs) are studied, using the binding isotherms.

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

On the Determination of Silica in Slag, Especially Chrome Slag
The Journal of the Japan Institute of Metals, 1949 At present, the determination of SiO2 in slag must depend upon the method of evaporation to dryness with HCl, but in the case of slag which contains too much Cr, it takes a long time to filter, and it is difficult to obtain the total SiO2 by once or twice dehydration.
