Lead oxide zinc ore VS lead sulfide zinc ore
1. The main components of lead-zinc oxide ore include cerusite and lead vitriol. These minerals are secondary minerals gradually formed under oxidation conditions of primary ores. Lead-zinc oxide ore is usually symbiotic with pyrite, siderite, etc., forming deposits such as limonite. Lead-zinc oxide ore has a wide distribution range, and due to its different origins, it is often enriched and mineralized in residual slope sediments. The main constituent minerals of lead-zinc sulfide ore include galena and sphalerite, which are primary minerals. Lead-zinc sulfide ore usually coexists with pyrite, chalcopyrite, etc. to form polymetallic ores. The reserves and distribution breadth of lead-zinc sulfide ores are much larger than those of lead-zinc oxide ores, so most lead and zinc metals are extracted from sulfide ores.
2. Physical properties, color and luster: The color of lead-zinc oxide ore is usually darker and may appear dark brown or black, and the luster is relatively weak. The colors of lead-zinc sulfide ore are more diverse, such as galena is lead gray, sphalerite is gray-black or black, and has a certain metallic luster. Hardness and specific gravity: The hardness of lead-zinc oxide ore is generally low and the specific gravity is relatively high. The hardness of lead-zinc sulfide ore varies depending on the type of mineral, but overall it has a certain hardness and a large specific gravity.
3. Formation process Lead-zinc oxide ore: Mainly based on lead-zinc sulfide ore, it is formed through long-term geological processes, such as oxidation, leaching, etc., which gradually transform sulfides into oxides. This process usually takes a long time and specific geological conditions. Lead-zinc sulfide ore: It is formed in a specific geological environment through natural processes such as hydrothermal action, sedimentation or volcanism. The origin of this type of ore is closely related to factors such as geological structure and magmatic activity.
4. Utilization value of lead-zinc oxide ore: Since the metal elements exist in the oxidized state, the extraction process is relatively simple, but the content may be low, which affects the extraction efficiency. However, its special physical properties and chemical composition make it valuable in certain specific fields, such as manufacturing special types of ceramics, coatings, etc. Lead-zinc sulfide ore: It is the main raw material for the lead-zinc smelting industry. It has high content and stable grade. It is the main source for extracting lead and zinc. The smelting process of lead-zinc sulfide ore is relatively mature and the extraction efficiency is high, so it has wide application value in industry.
5. Refining process Lead-zinc oxide ore: Since its metal elements exist in the oxidized state, it is usually refined using processes such as reduction or acid leaching. These methods can effectively reduce oxides to gold elements or dissolve them in acids for subsequent extraction. Lead-zinc sulfide ore: It is mainly refined through fire refining or wet refining. Fire smelting involves an oxidation-reduction reaction under high temperature conditions to convert sulfides into metal elements; hydrometallurgy involves the extraction of metals through chemical processes such as acid leaching.
