As an advanced structural material, FRP bars are made up of glass (GFRP), carbon (CFRP) or basalt fibers (BFRP) with epoxy or vinyl ester matrices. FRP bars possess many advantages, such as low density, high strength along fiber direction, ... the environmental impacts of mining sea sand were estimated according to [43,44]. …
Because this is a relatively new and experimental technique, much of the science around the environmental impacts of seabed mining is incomplete or unproven. But scientists have expressed serious concerns over the multiple potential impacts of seabed mining, from the noise of the machinery affecting wildlife, to the activity killing …

1. Introduction. To meet the demands of modern society, the mining industry must develop and integrate sustainable social, economic, and environmental principles across its life cycle (Asr et al., 2019; Aznar-Sánchez et al., 2019).Mining is reaching a weak sustainability position compared to other industries (Tost et al., 2018).Stone mining …
Green mining aims to adapt the mining operations to reduce the negative impacts, while maintaining the interests of stakeholders.Basalt is a mafic volcanic rock that is widely available in the Earth's surface and often occurs in a variety of ore deposit systems. Traditionally, basalt is used in various ornamentation and construction purposes.
Products. AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth.A quarry is a type of mine called an open-pit mine, because it is open to Earth's surface.Another type of mine, a subsurface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials. …
Magnesium hydroxide is a sustainable material for CO2 sequestration, according to an acid digestion and electrolysis method using olivine-rich silicate rocks in a fully recoverable system.
