Mar 17, 2014· These declarations appear to be based on the specific schedule for SAND in the IMSBC Code. This schedule is intended for five specific named grades of industrial sand (foundry sand, potassium feldspar sand, quartz sand, silica sand and soda feldspar sand) and refers to a need to keep the cargo as dry as practicable.
Feldspars and mica are also objectionable. Generally, iron content must be reduced to % Fe2O3 or less. Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than % Fe2O3.

That honor goes to feldspars. If the particular sand deposit contains almost nothing but quartz, we often call it a silica sand. Such sand deposits are said to be mature because other rockforming minerals are already broken down by the weathering process leaving only the superresistant quartz as a residue. Silica sand is a mineral resource.

Silicate minerals are rockforming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of the Earth's crust. In mineralogy, silica (silicon dioxide) SiO 2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.
