Overview of a quartz sand deposit and processing plant

Quartz sand deposit Ravno is the biggest quartz sand deposit in the Dolenjska region in Slovenia with an area of 1.25 km2. Quartz sand at the site is selectively excavated using mechanical methods. Presently, at the processing plant near the deposit, the main final mineral processing technique is flotation. Prior to the flotation, quartz sand undergoes classification and attrition.

Preparation and characterization of glass–ceramic foams

2015-9-26  Glass–ceramic foams were fabricated at a relatively low temperature by incorporating coal gangue, waste quartz sand and sintering additives in different proportions. Sintering and the foaming behavior of the foams were studied using thermal, X-ray techniques and morphological characterization, followed with physical and mechanical properties measurements. The effects of coal gangue content
