Chromium is a naturally-occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is mined in two different ways: underground mining and surface mining. Underground mining is used to reach deeper deposits. It involves digging a tunnel into the Earth, then blasting and excavating the ore.

by-product: [noun] something produced in a usually industrial or biological process in addition to the principal product.
chromium. chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated protective coating for other metals.

Natural gas is a relatively clean-burning fossil fuel. Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO 2) emissions than burning coal or petroleum products to produce an equal amount of energy. For comparison, for every 1 million Btu consumed (burned), more than 200 pounds ...
Moreover, the chromium in the wastewater containing about 35 mg/L was removed at a rate over 97.4%, and the Cr~(6+) content and total chromium were less than 0.50 mg/L and less than 1.0 mg/L, respectively, after treating using the optimized technological conditions. The treated water was qualified to the national discharge standard.

Mines rarely have control over the cost of energy, so it is vital that comminution processes meet process objectives while consuming as little energy as possible.
By-product. A by-product or byproduct is a secondary product derived from a production process, manufacturing process or chemical reaction; it is not the primary product or service being produced. A by-product can be useful and marketable or it can be considered waste: for example, bran, which is a byproduct of the milling of wheat into …
Phosphorus is an essential plant nutrient (the most often limiting nutrient, after nitrogen), and the bulk of all phosphorus production is in concentrated phosphoric acids for agriculture fertilisers, containing as much as 70% to 75% P 2 O 5. That led to large increase in phosphate (PO 4 3−) production in the second half of the 20th century.
