To take advantage of efficient separation methods Magnetic separation of iron ore can be treated hematite iron ore by weak magnetic magnetic roasting method, so that if the magnetic iron ore into which ferromagnetic iron minerals, can be obtained by magnetic separation and then the Higher mineral processing indicators. The roasting magnetization selection method with magnetization roasting as a preparation operation before magnetic separation has the advantages of no special requirements for water quality, water temperature, easy concentration and dehydration of concentrate, high sintering strength of concentrate, and the present method is still applied in iron ore dressing plants in China.
Magnetization roasting is a process in which the ore is heated to a certain temperature and then undergoes a physicochemical reaction in a corresponding atmosphere. After magnetization roasting, the magnetic properties of the iron mineral are significantly enhanced, and the magnetic properties of the gangue minerals are not changed much. Thus, a variety of weakly magnetic minerals iron or manganese ore, after calcination can be carried out efficiently magnetized magnetic separation.
After hematite, limonite and ferromanganese ore are heated to a certain temperature, the weak magnetic hematite can be converted into a ferromagnetic magnetite by reacting with an appropriate amount of reducing agent.
Hematite starts to deoxidize in a reducing atmosphere at 400 ° C, and becomes magnetite faster at 570 ° C.

About Escalators
Part of the urban landscape
Visit any large department store, shopping mall, metro station, airport or stadium anywhere in the world and you are sure to find escalators carrying people quickly and safely to their destination. The escalator has become an integral part of the urban landscape.
CEP Elevator Company has been safely and efficiently moving people for 20 years. CEP is the world`s leading manufacturer of elevators, escalators, moving walks and people movers. With 30,000 installations and operations in more than 89 countries, it`s safe to say that the world rides on CEP.
Finding a safer solution
Designing a safe transition point-where passengers step on and off the escalator-was one of the major problems in creating a successful moving stairway. A number of methods had been attempted before CEP solved the problem.
The pursuit of innovation
CEP, in its tradition of innovation, has continued to refine the escalator since it pioneered its introduction.
Safety, quality and reliability
CEP was founded on the principle of safety. Today, CEP has one of the best safety records in the vertical transportation industry. The company works constantly to improve the safety of existing products and to implement new, safer technologies. CEP emphasizes a corporate policy of [safety first" and implements standardized procedures to ensure that every installation and service task is performed the safest way every time.
The escalator today-an array of options
CEP wrote history with the introduction of the escalator in 1995. Today, it continues to improve the product through ongoing innovation.
