Iron Ore Crushing & Processing Copper Ore Crushing & Processing Silver Ore Crushing & Processing

The technological process for the metal ore designed by Zhongxin Heavy Industry, satisfies the client’s requirement greatly for the various metal ores crushing. The metal ore will be evenly conveyed by vibrating feeder to jaw crusher for primary crushing, the crushed material will be conveyed by belt conveyor to cone crusher for further crushing, material after being crushed will be conveyed to vibrating screen for screening, and material with qualified particle size will be conveyed by belt conveyor to final product pile; material with unqualified particle size will be back from vibrating screen to cone crusher for secondary and tertiary crushing, to achieve a closed circuit. Particle size of final product can be combined and graded according to the requirement of client.

01 THE COPPER ORE CRUSHING PROCESSING

PROCESSING TECHNOLOGY: Copper ore processing production process include: crushing, grinding, ore dressing three processes. Crushing process, the three sections of the closed-circuit is the most modern high-hardness copper ore crushing, to complete the ore crushing and partial dissociation of the work, thereby improving the follow-up grinding efficiency; grinding process, two-stage closed grinding efficient grinding process, you can make the copper mill more fully.

  • The first stage: copper ore crushing and screening Large pieces of copper ore from the silo by the vibrating feeder evenly into the jaw crusher / mobile jaw crusher for coarse crushing; coarse after the copper ore through the vibrating screen screening, by the belt conveyor To the single-cylinder hydraulic cone crusher (in the broken; after the broken copper ore material into the multi-cylinder hydraulic cone crusher for crushing;
  • The second stage: copper ore grinding Will be sifted through the vibrating screen of 0-12 mm copper powder evenly sent to the ball mill for grinding, and by the spiral classifier screening, does not meet the requirements of the ball mill is sent to continue grinding;
  • The third stage: beneficiation Will meet the requirements of the copper powder into the flotation machine for mixed flotation, and then get the copper powder into the dryer drying can get copper powder.
02 THE IRON ORE PROCESSING

PROCESSING TECHNOLOGY: According to the category and characteristic of ore, there are many different processes for iron ore dressing. In general, ore dressing plant may use primary, secondary and tertiary crushing processes for crushing iron ore. Jaw crusher is usually used for primary crushing; cone crusher is used for secondary and tertiary crushing. Through primary crushing, and then by secondary and tertiary  crushing, ore will be crushed to the suitable size for feeding ball mill.

  • The first stage: crushing and sieving - three sections of closed circuit Large pieces of iron ore from the silo by the vibrating feeder evenly into the jaw crusher or mobile jaw crusher for coarse crushing; coarse after the iron ore through the vibrating screen sieve, by the belt conveyor To the single cylinder hydraulic cone crusher in the broken; after the broken iron ore material into the multi-cylinder hydraulic cone crusher for crushing;
  • The second stage: milling Will be filtered through the vibrating screen 0-12 mm iron powder evenly sent to the ball mill for grinding, and by the spiral classifier screening, does not meet the requirements of the ball mill is sent to continue grinding;
  • The third stage: magnetic separation Will meet the requirements of the iron ore into the magnetic separator for magnetic separation, magnetic separation to remove debris;
  • The fourth stage: drying Will be the iron powder into the dryer drying can get iron powder.
03 THE SILVER ORE CRUSHING PROCESSING

PROCESSING TECHNOLOGY: Silver is commonly extracted from ore by smelting or chemical leaching. Silver involved in mixing silver ore, salt, copper sulphide, and water. A method called the cyanide, or heap leach, this process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores.

  • The first stage: crushing and sieving - three sections of closed circuit Large pieces of silver ore from the silo by the vibrating feeder evenly into the jaw crusher or mobile jaw crusher for coarse crushing; shredded silver ore after the sieve through the vibrating screen, sent by the belt conveyor Single cylinder hydraulic cone crusher in the crushing; crushing silver ore material into the multi-cylinder hydraulic cone crusher for crushing;
  • The second stage: milling Will be sifted through the vibrating screen 0-12 mm of silver powder evenly sent to the ball mill for grinding, and by the spiral classifier screening, does not meet the requirements of the ball mill is sent to continue grinding;
  • The third stage: beneficiation In the beneficiation process, due to the different types and properties of silver ore, the beneficiation method is also different, but commonly used re-election, flotation, mixed mercury, cyanide and today's resin slurry method, carbon paste adsorption, New technology of France. For some types of ore, often using the joint silver process.
