Technical Field

The invention relates to a method for on-line analysis of phosphate ore, which is suitable for on-line analysis of phosphate ore and other ore analysis, in particular to low-grade phosphate ore or other ore needing flotation.

Background

1. Current situation of phosphate ore

Phosphate rock plays an important role in national economy, and is particularly directly related to sustainable development of agriculture for agricultural countries with a large population. Due to over-exploitation in recent years, phosphorite resources have the phenomena of more serious enrichment and depletion, so that the phosphorite has low grade, more impurities, high mining and selecting cost and low recovery rate. Therefore, the reasonable development and utilization of phosphorite resources are very urgent problems.

2. Method for improving grade of phosphate ore

(1) The high-grade and low-grade phosphate ores are mixed, the grade of the low-grade ores is improved, the grade change of the ores needs to be monitored, and the cost is increased due to the excessive use amount of the high-grade ores; the use amount of the high-grade ore is too low, so that the quality of the ore is improved.

(2) The collecting agent is used for carrying out flotation on the phosphate ore, the grade of the ore is improved, the using amount of the collecting agent needs to be monitored in real time, and the quality of the phosphate ore is stabilized by the collecting effect.

3. The standard for stabilizing the quality of the phosphate ore is to control the contents of phosphorus, magnesium, iron, aluminum, calcium and the like in the phosphate ore, so the measurement of the contents of phosphorus, magnesium, iron, aluminum, calcium and the like in the phosphate ore is an effective means for ensuring the quality of the phosphate ore.

4. The method for measuring the contents of phosphorus, magnesium, iron, aluminum, calcium and the like in the phosphate ore comprises the following steps:

(1) the chemical titration method is also a national standard method at present, and from years of detection experiences, the repeatability of detection data is poor, the operation is complicated, the analysis time is long, and the human error is large.

(2) An ICP-AES method, which is used for carrying out quantitative analysis on characteristic spectrograms of magnesium, iron, aluminum and calcium by a plasma spectrometry; by consulting the spectrum line table, the sensitivity requirement of the potassium element analysis spectral line is higher, and the accuracy is easily influenced by the interference condition of the spectrum.

(3) The content of phosphorus is quantitatively analyzed by a spectrophotometer method through colorimetry, and the method has large errors in measurement of a large number of elements and poor reproducibility.
