At present, most of Yunxi Company has used the floating-heavy beneficiation process of Daxie Concentrator's sulphide ore workshop for more than 30 years (Fig. 3.13.5). The process is: the original ore is crushed to 20mm, and a closed-circuit grinding to 0.074mm (200 mesh) accounts for 60%. %～65%, mixed flotation, one coarse and two sweeping one fine; copper sulfur separation grinding to 0.074mm accounted for 95% one coarse two sweeping three fines, copper concentrate, sulfur concentrate; mixed flotation tailings and then selected sulfide After re-election. After the first and second stages of bed selection; one re-washing; mud selection; tin coarse concentrate desulfurization flotation, tin concentrate, rich medium ore.
Changpo Concentrator is one of the selected factories of Dachang Mining Bureau. First, the raw ore is crushed to -20mm and then sieved into two grades of 20~4 and 4~0mm, and 20~4mm is preselected into the heavy medium cyclone. The heavy medium cyclone heavy product is pre-selected by jigging after a rod mill. The jigging tailings is screened with 2mm vibrating screen to remove +2mm as waste tailings, and -2mm into the shaker. The jigging and shaker concentrates and medium mines are divided into two systems based on grades, which are regrind and mixed flotation. Flotation tailings shaking sorting Conformanceand tin concentrate; mixed and then finely ground flotation concentrate for flotation separation of lead zinc, antimony and lead, respectively, outputs concentrate and zinc concentrate. The re-selected slime enters the Φ300mm cyclone, and the overflow is removed by the Φ125 and Φ75mm hydrocyclones. The sedimentation is concentrated and floated for desulfurization.
A fertilizer or fertiliser is any material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants.
Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration. This article, like many on fertilizers, emphasises the nutritional aspect. Fertilizers typically provide, in varying proportions.
Fertilizers are classified in several ways. They are classified according to whether they provide a single nutrient (e.g., K, P, or N), in which case they are classified as "straight fertilizers." "Multinutrient fertilizers" (or "complex fertilizers") provide two or more nutrients, for example N and P. Fertilizers are also sometimes classified as inorganic (the topic of most of this article) versus organic. Inorganic fertilizers exclude carbon-containing materials except ureas. Organic fertilizers are usually (recycled) plant- or animal-derived matter. Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture.
We mainly supply Phosphate fertilizer, such as: MAP, MKP and Silicate fertilizer, like: Potassium Silicate
