The natural world is often lead zinc ore symbiotic together, are generally mineral flotation with due process. I.e. after crushing the ore to a particle size selected to a certain other low-grade waste rock large dense media, then the flotation process The ore that has been enriched. Heavy medium beneficiation is generally divided into four steps: ore preparation, second, selection of heavy medium suspension of galena, third, heavy medium for removing two products on the sieve, and fourth, recycling of heavy medium. In the first step, the ore of -25 mm is sieved, and the sieved material of less than 4.5 mm is dehydrated and sent to the grinding. The product on the sieve enters a shallow and wide chute, the bottom of the tank is a dewatering sieve, and the dehydrated product enters the belt. Sorted in a pyramidal heavy medium concentrator with a promotion ore discharge device, the floating material (ie abandoned tailings) enters the medium along a chute to remove the heavy medium on the sieve, and then enters the silo. The sinking object falls on the corner. In the lower part of the cone chamber, the dewatering bucket is transported out in the chute and then into the medium removal screen. The heavy medium on the ore is removed from the first two sections on the screen, and washed on the third and fourth sections. The heavy medium attached to the ore, the fifth section of the sieve is used to remove the washing water. The enriched ore after washing is put into the warehouse. The heavy medium removed by the medium is removed by the medium, and the material larger than 0.5 mm is removed by vibration, and In this sector, the sieve returning medium is removed from the sieve, and the sieved product is divided into three sections by a distributor. One of the large parts is returned to the heavy medium concentrator, and a small department is sent to the flotation machine to float the galena and return to the medium for storage. The weight of the heavy medium (galena) used for heavy medium ore dressing is 2.92 and the viscosity is 1.45. The grade of galena used to prepare the heavy medium is higher than 72% Pb to ensure that the viscosity of the resuspension is not large. When the content of fine float galena in the heavy medium is large, the adhesion is too large. When the coarse particles are too much, the sticking is too low, and the weight of the dry lead ore lost by one ton of waste rock is 0.03 kg. Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
