Data Source
The source of data for the expanded perlite end-use worksheet is the Mineral Yearbook, an annual collection, compilation, and analysis of mineral industry data, published by the U.S. Bureau of Mines and the U.S. Geological Survey.
End Use
End use is defined as the use of the mineral commodity in a particular industrial sector or product. Expanded perlite end-use categories are based on sold or used by producers. For expanded perlite end-use categories are concrete aggregate, fillers, filter aid, formed products, horticultural aggregate, laundries, low-temperature insulation, masonry and cavity-fill insulation, plaster aggregate, and other industrial uses.
The apparent consumption category applies to processed crude perlite and is not the apparent consumption of expanded perlite. Processed crude perlite is the “feedstock” for expanded perlite. Apparent consumption is calculated by adding the amounts of processed crude perlite sold or used in the U.S. together with imports and subtracting exports.
The undistributed category accounts for processing loss and stock changes. It is the difference between the apparent consumption of processed crude perlite and the total use of expanded perlite. These numbers are comprised of three parts. As crude processed perlite is expanded, the contained water (normally in the 2 percent to 5 percent range) is driven off and removed from the expanded perlite. Additionally, an indeterminate amount of crude processed perlite does not expand and is leftover as “waste” material. The last fraction in this category is crude processed perlite that is held in stockpile.
The horticultural aggregate category includes fertilizer carriers. The formed products category includes acoustic ceiling panels, pipe insulation, roof insulation board, and unspecified formed products. The other uses category includes fines, explosives, high-temperature insulation, paint texturizer, refractory, soap, steel, sugar manufacture, and various non-specified industrial uses.
Blank cells in the spreadsheet indicate that data were not available. Data are rounded to no more than three significant digits; data may not add to totals shown.
