The expansion of Silica Sand is compared below against the popular "Special Refractory Sands" such as Chromite and Zircon. IMPURITIES CONTAMINATES AND TESTING PROCEDURES The Acid Demand Value test: The acid demand value is important because it displays the amount of alkaline materials that should not be present in washed and classified ...
The values of thermal conductivity of the molds which consisted of silica, zircon, chromite sands decrease gradually from room temperature to 1,000°C. The mean values of thermal conductivity of these molds are unit for silica sand, unit for olivine sand, unit for zircon sand and unit for chromite sand.

silica, olivine and chromite. The newly created, less angular grains have a reduced surface area that requires less binder. Technical Article | 02. Fundamentals of Sand Reclamation How easily the acid alyzed furans and phenolics on reclaim depends primarily on how much resin is used to bond the sand and how much resin is burned away by casting operation. Experimental data and experience in ...
chromite sand quality parameters at each step within the plant together with the measuring of all sand flow rates led to the reconstruction of separation efficiency at each step of chromite processing. The results of grain size, XRD, XRF, EMP and grain counting analyses together with separation efficiency (SE) and liberation degree (LD) evaluation allow to conclude that Brieville plant does ...
