Research on regeneration methods of animal glue waste sand for foundry [PDF]
Royal Society Open Science, 2018 Sand moulds are used in the casting process. However, after heating, the binder in the sand loses the binding properties, and the most part of the foundry sand has to be discarded from the process.

Assessment of Foundry Chromite Sand Crushability under Thermal-Mechanical Loading [PDF]
Archives of Foundry Engineering, 2023 When used for sand casting, foundry sand is stressed in several ways. These stresses, thermal and mechanical, compromise the grain integrity, resulting in size reduction and the production of small particles to the point where the sand is no longer ...

Can waste foundry sand fully replace structural concrete sand? [PDF]
Journal of Material Cycles and Waste Management, 2018 Foundry sand (FS) waste creates a serious solid waste management problem worldwide due to the high volumes produced, necessitating alternatives to landfilling. A possible route is its use in concrete; however, the current consensus is that FS can only be used for modest sand replacements, based mostly on evidence on concrete with clay-bound FS ...

Recovery of Silicon Dioxide from Waste Foundry Sand and Alkaline Activation of Desilicated Foundry Sand [PDF]
Journal of Sustainable Metallurgy, 2020 Abstract This study was conducted to recover silica (desilication) as a valuable metalloid from waste foundry sand (WFS) by a leaching process and to find application for desilicated foundry sand (DFS). The leaching time applied was 5 h; 3 M of potassium hydroxide (KOH) was used as a leaching reagent.
