ore processing equipment manufacturer
Major rock types processed by the crushed stone industry include tantalite, limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Major mineral types processed by the pulverized minerals industry, a subset of the crushed stone processing industry, include calcium carbonate, talc, and barite. Depending on years¡¯ abundant production experience and high technology, ZENITH has produced the tantalite beneficiation plant machine for the worldwide customers.
tantalite crushing processing
Quarried tantalite normally is delivered to the processing plant by truck and is dumped into a bin. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher. Jaw, impactor, or gyratory crushers are usually used for initial reduction. The crusher product, normally 7.5 to 30 centimeters (3 to 12 inches) in diameter, and the grizzly throughs (undersize material) are discharged onto a belt conveyor and usually are conveyed to a surge pile for temporary storage or are sold as coarse tantalites.
In the tantalite beneficiation production process plant, for example, tantalite ore is up graded to higher content through concentration. Tantalite ore is beneficiated to all around the world to meet the quality requirement of large steel industries. Several technologies are available such as washing, jigging, magnetic separation; advance gravity separation and flotation are being employed to enhance the quantity of the iron ore. Recent increase in demand for steel and increase in its costs has boosted up the production of iron and steel. The demand for tantalite ore also has sharply increased. The good quality tantalite is fast depleting thereby forcing the iron makers to use low grade one after beneficiation.
Techniques for processing tantalum-niobium ore
Generally, in the first step, we adopt gravity concentration to dispose of most gangue minerals to get low grade mixed ores. In the process of concentrating ores, the separation can be very difficult due to the complicated composition of the mixture that contains various kinds of useful minerals. There are many ways to process tantalum-niobium ores, including gravity concentration, flotation, electromagnetic separation or dressing-metallurgy combining technique. We can utilize one or more of these techniques to separate the minerals.
Gravity concentration is often used in roughing separation of tantalum-niobium ores. And in the concentrating of ores, we often adopt gravity concentration, flotation, electromagnetic separation or dressing-metallurgy combining process. Ore washer and efficient ore grinder and grader are also utilized to increase the fineness of ores.
