The basalt stone be mined from basalt mining should be transported into basalt jaw crusher, basalt impact crusher, basalt cone crusher for the primary crusher by belt conveyor. After How crushed rocks can help capture ,The principle behind this negative emission technology is to enhance the natural reaction of CO 2 with rocks and minerals on the Earth's surface as they break Basalt an overview ScienceDirect Topics,Basalt is the most widely distributed basic extrusive rock, with a SiO 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. Pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needlelike
