Usually copper ore processing plant, generally applied to the peripheral drive device selected from the group of copper concentrator; second stage selected from the folding device uses copper belt vacuum filter, processing equipment is selected from iron ore using a cylindrical inner filter type vacuum filter, since the filter required technical parameters of different devices, thus matching vacuum filtration system configured auxiliary equipment are different. The use of beneficiation equipment to reduce the gold content of the sulfur concentrate has become a prominent problem. Through the mineral processing equipment, through a discussion on a treatment scheme such as grinding, cyanide leaching, amalgam flotation, and stage flotation, the ore dressing equipment was sought in a reasonable selection scheme and achieved good indicators. When the copper-selecting equipment is sorting a certain brownstone sulfide ore, the heavy-precision reverse flotation test method of first re-election and flotation is used to improve the quality and recovery rate of the brown concentrate. Since the mineral contains brownstone and sulfide ore, the concentrate obtained by re-election contains sulfide ore which cannot be separated by Dali, and affects the quality of the brown concentrate. The flotation of the easily floatable ore is then selected by flotation, and the remaining in the flotation tank is the enriched brown concentrate. On the one hand, the contradiction between supply and demand of iron ore in China is increasingly prominent. On the other hand, it faces the reality that domestic rich limonite resources are not well utilized. In this case, the technology of limonite pellet processing equipment should be carried. Health. At present, China's siderite and limonite are mainly used as sintering raw materials, but the addition of sinter will lead to a decline in the quality of sinter minerals. The roasting of pellets with a sintering machine has quietly emerged in recent years and has become a technology used in new beneficiation production lines . The process has been successful in producing acidic oxidized pellets from magnetite and hematite. When the limonite pellet is fired by the sintering machine, the sintering speed is fast, and thus the high temperature holding time is short, so the pellet strength is not high.
Urea-formaldehyde resin (UF), also known as urea-formaldehyde resin, is a polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acid catalyst) to form an initial urea-formaldehyde resin, and then under the action of a curing agent or auxiliary agent to form an insoluble and insoluble final stage Thermosetting resin. The cured urea-formaldehyde resin is lighter in color than phenolic resin, translucent, resistant to weak acid and alkali, has good insulation performance, excellent wear resistance, and is cheap. It is the most used type of adhesive, especially in the wood processing industry. In the manufacture of various wood-based panels, urea-formaldehyde resin and its modified products account for about 90% of the total amount of adhesives. However, urea-formaldehyde resin is easily decomposed in the presence of strong acid and strong alkali, and has poor weather resistance, poor initial viscosity, large shrinkage, high brittleness, water resistance, and easy aging. The wood-based panels produced with urea-formaldehyde resin have formaldehyde release in the process of manufacturing and use. problem, so it must be modified.
