[0041] Example 1
[0042] Such as image 3 Shown is a LIBS online detection system for phosphate ore beneficiation system. The system consists of sampler 1, multiplexer 2, LIBS analyzer 3, sand pump 4, reservoir 5, DCS control system, sampling Device 1 communicates with the inlet of the multiplexer 2 through the pipeline, the outlet of the multiplexer 2 communicates with the inlet of the LIBS analyzer 3 through the pipeline, and the outlet of the multiplexer 2 communicates with the storage through the pipeline. The inlet of the liquid pool 5 is connected, the outlet of the liquid reservoir 5 is connected to one end of the sand pump 4 through a pipeline, and the other end of the sand pump 4 is connected to the raw ore inlet through a pipeline; the outlet of the LIBS analyzer 3 is connected to the raw ore inlet through a pipeline The liquid storage tank 5 is connected to the inlet, the LIBS analyzer 3 is connected to the DCS control system signal, and the sample analysis data is tr...

[0045] Example 2
[0046] Such as Figure 4 As shown, the online detection system described in Example 1 is used in the positive-reverse flotation phosphate ore beneficiation system to process 1.5 million tons / year of low-grade collophane (raw ore P 2 O 5 Grade 18-22%, MgO grade 4%-6%), the specific steps are as follows:
[0047] 1) Sampling: respectively at the positive flotation roughing raw ore sampling point ⑤, positive flotation concentrate sampling point ⑧, positive flotation tailings sampling point Sampling point of reverse flotation concentrate Sampling point of reverse flotation tailings Set up the sampler 1, open the control valve 11 of the sampler 1 at each sampling point in order to take samples, and get the sample through the pump 12 and pump it into the inlet of the multiplexer 2;
[0048] 2) Sample preparation analysis: After the multiplexer 2 is reduced, the sample is sent to the LIBS analyzer 3 for on-line detection and analysis of indicators, the remaining materia...

[0053] Example 3
[0054] Such as Figure 5 As shown, the online detection system described in Example 1 is used in a single reverse flotation phosphate ore beneficiation system to process 3 million tons / year of low-grade collophane (raw ore P 2 O 5 Grade 18-22%, MgO grade 4%-6%), the specific steps are as follows:
[0055] 1) Sampling: Sampling was set up at the original ore sampling point I, reverse flotation tailings sampling point III, reverse flotation selection tailings sampling point IV, reverse flotation ore sampling point V, and reverse flotation tailings sampling point VI. Device 1, open the control valve 11 of the sampler 1 at each sampling point in sequence to take samples, and get the sample through the pump 12 and pump it into the inlet of the multiplexer 2;
[0056] 2) Sample preparation analysis: After the multiplexer 2 is reduced, the sample is sent to the LIBS analyzer 3 for on-line detection and analysis of indicators, the remaining materials are sent to the reser...
