Natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk

cpc code 1611 covers the extraction and processing of natural calcium phosphates, natural aluminium calcium phosphates, and phosphatic chalk. These materials are essential raw materials for a variety of industries, including agriculture, chemical manufacturing, and construction. They play a crucial role in the global economy, providing key inputs for the production of fertilizers, animal feed, and other important products.

The production of materials under cpc code 1611 typically involves the mining and processing of natural mineral deposits. This may include techniques such as open-pit or underground mining, followed by crushing, screening, and beneficiation processes to concentrate the desired phosphate-containing minerals. In some cases, further chemical treatment may be required to produce specific phosphate compounds or derivatives.

The main inputs for the industries covered by cpc code 1611 include the natural mineral deposits containing calcium phosphates, aluminium calcium phosphates, and phosphatic chalk. These raw materials are typically extracted from geological formations, often in regions with significant phosphate reserves. In addition to the mineral resources, the production process may require various types of mining and processing equipment, as well as energy sources and water for the extraction and beneficiation operations.

The primary outputs of the industries under cpc code 1611 are the various forms of natural phosphates, including 2515 Phosphoric acid and polyphosphoric acids, 2517 Calcium phosphates, aluminium calcium phosphates and phosphatic chalk, and other phosphate-based products. These materials are then used as inputs for a wide range of downstream industries, such as 2010 Manufacture of basic chemicals, fertilizers and nitrogen compounds, plastics and synthetic rubber in primary forms, 1011 Processing and preserving of meat, and 2332 Manufacture of bricks, tiles and construction products, in baked clay.
