Magnetic separation is realizing the mineral processing according to the magnetic differences between minerals from magnetic and other mechanical force. At present, it is used in the processing of ferrous metal and non-metal, and the fine processing of non-ferrous metal and precious metal.
Recently, 2019 the 4th International Mining Property Information Conference is convened in Xi’an. It is pointed at pushing the communication of mining property information, resource development and trade negotiation with the topic “pushing the cooperation of mining properties and win-win in the future”. Over 240 mining company and over 600 colleagues in mining industry took part in this conference from home and abroad. The participants are from Canada, Russia, Australia and other 15 countries and regions.
In mineral processing plant, vibrating screen is one of the common classifiers, which has large influence on the following works. Therefore, how to improve the screening effect is one of important problem to be concerned. In this paragraph, we will analyze what the factors are and how they influence the vibrating screen.
With the privation of mineral resource, the intelligence and enlargement of mineral processing equipment, and the development of mineral processing equipment, there are higher requirements of the efficiency, reliability, stable process parameters, and product qualities in processing plant. Therefore, the mineral processing automatic control system is promoted, which is steadily becoming the essential technology of modern mineral processing. At present, the mineral processing automatic control technology becomes the essential and effective way realizing mineral processing plant normal production and the improvement of mineral processing plant efficiency.
Recently, Xinhai Mining received the thanks letter from 1500tpd Pakistan copper processing project. In this letter, they expressed the praise to the technology skill, professionalism and duty of Xinhai Mining process commissioning team.
In mineral processing proceeding, ores need to be grinded into a certain size for the complete separation of fine grain size mineral production and gangue minerals, and over-grinding should be avoided at the same time in case of the effect of sliming. The production below standard should be sent to mill for circular grinding, while the qualified product should be separated to extraction period in time and avoid unnecessary grinding. Therefore, classification takes an important part in grinding operation from technology and economy aspect.
On November 6-7th, Xinhai Mining carried out safety production training for all staff, to put the requirement “Big Study, Big Training, Big Exam” special action implementation plan of State Administration of Work Safety in practice, to strengthen the consciousness of safety production, and in case of safety accident.
Far from Sudan in Northeast Africa, there is a vast territory with a sparse population and various resources. According to the statistics, Sudan has rich mine resources, especially gold and chrome. Other explored minerals includes silver, iron, copper, aluminum, mica, asbestine, talc, tungsten, zinc, diamonds, uranium and so on. It is actually a large mine country in Africa. However, the simple economy structure, behindhand industry basis and mineral processing technology limited the mine industry development in Sudan. Therefore, Sudan mine industry largely depends on foreign countries, which market has a large potential development.
In the grinding operation, the consumption of steel ball is very large, which is about 10 times more than the loss of ball mill liner. In order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a certain ratio.
Flotation machine is one of the most common mineral processing equipment used for separating copper, lead, zinc, nickel, gold, which can be divided into mechanical agitation flotation machine and air inflation flotation machine. The working principle of flotation machine is that the v-belts of rotating motor drives the impeller to rotate and form the negative pressure, so the air mixes with pulp and reagent, then forming the fining foam. The mineral adheres on the foam, and generates the mineralized foam layer on the surface of the pulp and then the foam is scraped by the scraper blade under the certain height of the control page.
