Yuding Lead-Zinc Mine Concentrator (1)
The factory was designed in the 1950s and put into production in 1960. The design scale is 600t/d. In 1985, the actual processing capacity reached 722t/d. (2) Process flow: The process of crushing and screening is shown in the following figure: Reflex sights, also known as red dot sights, are a type of non-magnifying gun sight used on firearms to improve target acquisition and accuracy. They work by projecting an illuminated aiming point, such as a red dot or a green dot, onto a lens that the shooter looks through. This dot is aligned with the firearm's barrel, allowing the shooter to quickly and accurately aim at the target.

(1) The nature of the ore: Ore Processing plant belonging mesothermal filled fractures lead zinc deposit account. The mine is divided into two mines, the South and the North. The ore is divided into three types: sulfide ore, oxidized ore and mixed ore. The zinc oxidation rate is 13%, and the lead oxidation rate is greater than 22%.
The main metal minerals galena, sphalerite, pyrite, calamine, zincite, willemite, hydrozincite, white lead ore, lead sulfate, lead jarosite, limonite and erythro Iron ore. The gangue minerals are mainly calcite , dolomite, barite , gypsum , kaolin and the like.
Lead-zinc sulfide ore mainly refers to the enrichment of lead-zinc ore and disseminated ore. The enriched lead-zinc ore is densely packed, and the sphalerite and galena in the dip-coated ore are star-shaped or vein-like. The maximum size of galena is 12mm, the minimum particle size is 0.01mm, the maximum size of sphalerite is 20mm, and the minimum particle size is 0.01mm.
The structure of lead-zinc ore is relatively complicated. The zinc-containing oxide is plate-shaped, columnar, stalactite, grape-like, radial and fibrous, and is filled in rock cracks and limonite pores, in addition to mutual symbiosis, and clay , limonite, calcite, white mica, etc. cerussite intimately associated, the crystal grain size is generally 0.3 ~ 0.01mm. The crystal size of the lead-containing oxidized mineral is very fine, generally 0.02 to 0.01 mm.
The ore density is 3.03~3.1t/m3, the loose density is 1.7~1.8t/m3, and the hardness is 7. The ore contains 3 to 5% water and contains more than 5% mud. The multi-element analysis of lead ore, lead phase analysis and zinc phase analysis are shown in the following table: 
Reflex sights offer several advantages over traditional iron sights, including:
Faster target acquisition: The illuminated dot is easy to see and enables the shooter to quickly acquire and maintain a sight picture on the target.
Improved accuracy: The simple, uncluttered sight picture helps shooters maintain proper sight alignment and focus on the target.
Better low-light performance: The illuminated dot is more visible in low-light conditions compared to iron sights.
Unlimited eye relief: Reflex sights don't require the shooter to maintain a specific distance between their eye and the sight, providing more flexibility in terms of shooting positions and firearm configurations.
Reflex sights are popular among recreational shooters, competitive shooters, and law enforcement officers for their ease of use and accuracy improvements. They are commonly used on handguns, rifles, and shotguns.
