Dragline excavator

A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining . Draglines fall into two broad egories: those that are based on standard, lifting cranes, and the heavy units which have to be built onsite. Most crawler cranes, with an added winch drum on the front, can act as a dragline. These units (like other cranes) are designed to be dismantled and ...

How is Iron Ore Mined

 · Open pit mining is used for the production of iron ore. Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the ...

Mechanized mining is executed by the extraction of iron ore from surface deposits. The mining areas require all the operations to be mechanized and mining is exceptionally done through systematic formation of benches by drilling and blasting. The physical processes are followed which then remove impurities and the processed ore is stockpiled and blended to meet product quality requirements and ...

Flotation Reagents Collectors | ArrMaz

The surface properties of a mineral determine its ability to float. Collectors, some of the most important flotation reagents used in the flotation process, are used to modify the surface properties of minerals. A collector is a chemical that selectively binds to the surface of target minerals and imparts hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.
