Sustainability in the steel industry. Steel is an iron-carbon metallic composition with high mechanical strength, good malleability, ductility, and, depending on the alloy, good corrosion resistance, especially when coated or treated to obtain protection against oxidation (Raabe et al. 2019).These characteristics make steel a widely …
According to a senior executive at mining major, BHP, India's production of steel might double to 500 million tonnes by 2050, roughly four times the current output, as New Delhi strives to support its apparent economic ambitions with quick capacity expansion for the principal infrastructure alloy.
Lithium mining from ore deposits combines traditional mining techniques, including drilling, blasting, and excavation. Once the lithium-rich ore is extracted from the ground, it undergoes physical separation processes to remove impurities, concentrating the valuable lithium minerals. What is the process of mining lithium from evaporating ponds?

Steel is used everywhere. Steel production is dirty business - yet no-one can make a product without using steel. If steel is not used in a product, it is used in the production or shipment of products. But steel can be produced in much friendlier ways… Good example of greener steel production
The increasingly stringent European regulation and the ever-higher disposal costs currently affect manufacturing industries, leading them to strengthen their efforts in order to improve the recycling rate of their by-products …
Mapped: US non-fuel mineral production, by state. Just how many minerals does the US consume? In 2020, non-fuel mineral consumption worked out to around 19,000 pounds or 8.6 tonnes per person.
Continuous casting is a method used to produce large, continuous lengths of steel. In this process, the molten steel is poured into a water-cooled copper mold, which helps solidify the steel into a semi-finished form. As the steel solidifies, it is continuously pulled out of the mold, resulting in a continuous strand of solid steel.
After solution mining, the potash-rich brine is transferred to processing facilities for further treatment. The processing steps are designed to remove impurities and concentrate the potassium salts into a marketable product. The following sub-sections describe the typical processing steps involved in producing potash from solution mining.
It saves an enormous amount of energy and water, and the mining of iron ore is not necessary. CO2 reducing. Steel recycling avoids almost 950 million tons of CO2 emissions, 1 billion tons of iron ore, and the energy equivalent to burning about 280 million tons of coal (compared to producing the steel from mining of metal ore). Closed loop ...
The lack of consensus on what defines greenness for steel is further complicated by the fact that steel is currently produced using two routes: a primary (integrated) route which is highly emissions-intensive, and a secondary route which uses recycled steel and is much less emissions-intensive (global averages of 1.85 tCO 2 /t …
