Abstract

The invention discloses an LIBS online detection system for a phosphate ore beneficiation system and an application of the LIBS online detection system, and relates to the technical field of phosphateore beneficiation. A sampler is arranged on a pipeline of a beneficiation system, wherein the sampler is used for sampling ore pulp flowing through the pipeline and then pumping the ore pulp into a multi-path splitter; the multi-channel splitter is used for dividing the sample into small samples, feeding the samples into a LIBS analyzer for detection analysis, and sending redundant parts directlyinto a liquid storage tank. After analysis, the sample is also sent into a liquid storage tank, and then pumped into a raw ore feeding port through a sand pump, and enters a beneficiation system. After the samples are analyzed, the samples enter the beneficiation system again, and the raw ores are not wasted. Meanwhile, the links of manual sampling, sample preparation and detection are avoided, and the sample analysis time is shortened. The sample analysis data is uploaded to a DCS in real time, so that technicians can conveniently regulate and control the reagent in real time, the automationand intelligentization of the beneficiation system are improved, the more refined control is achieved through online detection, the quality stability of the finished product concentrate is guaranteed, the grade of the phosphorus concentrate product is improved, wherein P2O5% of the concentrate product is more than or equal to 28.5%, and MgO is less than or equal to 0.8%.

Description

technical field [0001] The invention relates to the technical field of phosphate ore beneficiation, in particular to a LIBS online detection system for a phosphate ore beneficiation system and its application. Background technique [0002] my country has abundant reserves of phosphate rock resources, but the reserves of high-grade phosphate rock are low. At present, the average grade of phosphate rock in my country is only 16.95%, and a large number of them are low- and medium-grade phosphate rocks, of which 80% have not been effectively developed. Utilization, collophanite is a typical low-grade phosphate rock. On the other hand, in order to meet the needs of the domestic market, a large amount of phosphate fertilizers are imported every year. In order to solve the fundamental way of this contradiction between supply and demand, it is the key to overcome the development of low-grade phosphate rock resources in my country. [0003] At present, there are two kinds of mixed t...
