What Is Silica Sand & How Is It Different From .

The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource. In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as what's often called 'regular' sand. How Silica Sand Is Different From Regular Sand . Regular
