How is iron ore removed from the ground?
Most mineral ores exist as a compound - commonly an oxide or a sulphide, but others are known. If an oxide, then heating say, the iron ore in a reducing environment will remove the oxide. If a sulphide, then simple heating may suffice. It is just a matter of finding a chemical reaction that will remove the unwanted material.
How can you increase the velocity of the ore?
It isn't clear what situation you are talking about. Velocity of the ore, where exactly?
What is the energy source for a vein of ore underground?
What is th see energy source for a vein of ore that is formed underground
What does iron ore feel like?
hard
Is aluminum ore the same a aluminum?
No. Aluminum is a metal. The ore from which aluminum is refined is called bauxite. It is abundant in Jamaica, among other places.
What is used in a flotation cell to separate a metal compound and its ore?
Its the froth mechanism in the flotation cell.
Why does the ore need to be freshly ground for the flotation?
the ore needs to be freshly ground for the floatation to increase the surface area.
How is sphalerite formed?
Sphalerite is sulphide ore, it is concentrated by froth flotation and then subjected to roasting to convert the sulphide ore to oxide ore. The oxide ore is reduced to zinc using carbon monoxide or coke.
How is phosphorus obtained?
Phosphorus is obtained from phosphate deposits. Phosphate ore beneficiation methods have been continuously enriched in the development. The traditional beneficiation methods include: scrubbing and desliming process, gravity separation, flotation, gravity-magnetic-flotation combined process and roasting process. Scrubbing and desliming process: for ores with a high degree of weathering. Gravity separation: The proportion of main gangue minerals in phosphate rock is similar to that of apatite. In industrial practice, dense medium separation is mainly used. Flotation: Flotation has always been the main method for beneficiation of phosphate ore, especially for complex and difficult ores. Such as positive flotation, single reverse flotation, positive one negative (negative one positive) flotation, double reverse flotation. Roasting method: It is a fairly mature method used in industry to completely remove carbonate from phosphorite ore.
What is beneficiating?
brifely explain the iron ore benification process
What is always a property of an ore?
Iron
How do you extract gold from copper ore?
Typically, you would use a flotation process to concentrate the copper and gold. Concentrate would be shipped to smelter for recovery of metals.
The loadstone a species of iron ore which has the property of attracting iron?
Magnet
What is classification in terms of mineral beneficiation?
It depends the chemical and physical properties of the raw materials. Beneficiation Equipment can be divided into Flotation Machine, High-frequency Screen, Hydrocyclone, Magnetic Separation Machine, Spiral Classifier. Flotation machine are mainly used in mineral ore dressing plants, selecting the valuable mine from gangue. It is applicable for the separation of numerous of mineral ores, such as fluorite and talc, gold ore, copper ore, iron ore and zinc ore and so on. High-frequency screen is a good choice for screening and grading the fine particles of mineral ores. This machine has wide application in iron ore, tin ore, tungsten ore, tantalum ore, dolomite sand and some other kinds of mining dressing plants' screening and grading work. Hydrocyclone has wide application in metal ore and nonmetal ore processing plants, such as plants of iron ore dressing industry, manganese ore beneficiation industry, coal industry, environmental power, alumina industry and some other mining industries. Magnetic separator is mainly used in wet separating of the fine minerals with strong ferromagnetism. The wet-type drum permanent magnetic separator is mainly suitable for wet separating of the following ores with the sizes less than 3mm, which are magnetite, magnetic pyrite, baking ore, and limonite and so on.
Why is the froth flotation method selected for the concentration of sulphide ores?
This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the water. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence this method is suitable for the concentration of the sulphide ore
What can't be separated by physical means?
Copper chloride iron and iron ore
Are hurricanes or tornadoes ore dangerous?
Yes. Hurricanes and Tornadoes are dangerous. they can destroy property and life.
