specific Embodiment approach

[0014] (1) Take raw ore of yellow phosphorus ore with loss on ignition ≥ 5% and diameter ≤ 300mm, or concentrate of yellow phosphorus ore with loss on ignition ≥ 5% and diameter of 15-80mm after processing, and calculate the unit by chemical analysis The quantity of yellow phosphorite heated to 1100°C requires heat and the heat content of the fuel used, and the ratio of required heat to available heat is 1:1.05 to obtain the weight ratio of yellow phosphorite to fuel, and according to this The proportion of yellow phosphorus ore and fuel is continuously added to the heating device;

[0015] (2) Control the temperature in the heating device within the range of 900°C to 1100°C for 60 to 90 minutes;

[0016] (3) After cooling the heated yellow phosphorus ore to a temperature of ≤80°C; the raw ore is crushed and screened and transported to the storage bin for standby, and the yellow phosphorus ore concentrate is directly transported to the storage bin for standby.

Embodiment 1

[0020] Take the raw ore of yellow phosphorus ore with loss on ignition ≥ 5% and diameter ≤ 300mm, calculate the heat required to heat a unit amount of yellow phosphorus ore to 1100°C and the heat content of the fuel used, according to the required heat and The ratio of available heat is 1:1.05, and the weight ratio of yellow phosphate ore and fuel is obtained, and the yellow phosphate ore and solid fuel are continuously added to the smoke-reducing heating device according to this ratio; then the heating temperature is controlled to 1100°C, Keep it for 90 minutes; cool the heated yellow phosphorus ore to 80°C, crush and screen it and transport it to the storage bin for standby.

Embodiment 2

[0022] Take the raw ore of yellow phosphorus ore with loss on ignition ≥ 5% and diameter ≤ 200mm, calculate the heat required for heating a unit amount of yellow phosphorus ore to 1050°C and the heat content of the fuel used, according to the required heat and The available heat ratio is 1:1.05, and the weight ratio of yellow phosphate rock and fuel is obtained, and the yellow phosphorite and gas fuel are continuously added to the trolley heating device according to this ratio; then the heating temperature is controlled to be 1050°C, and the 90 minutes; after cooling the heated yellow phosphorus ore to 80°C, it is crushed and screened and transported to the storage bin for standby.

Abstract

The invention discloses a yellow phosphorus ore processing technology, which comprises the steps of: continuously adding yellow phosphorus ore and fuel into a heating device according to calculated proportions, controlling the temperature of the heating device to be within a range of 900-1100 DEG C for 60-90min, and finally transporting the yellow phosphorus ore to a storehouse for future use after the heated yellow phosphorus ore is cooled to be less than or equal to 80 DEG C. The yellow phosphorus ore processing technology has the advantages that the carbonate and the crystal water in the yellow phosphorus ore can be effectively removed; compared with the relevant economic indicators of the existing yellow phosphorus production method, the power consumption per unit product can be decreased by 15-18%, the coke consumption is decreased by approximate 15% and the yield is improved by approximate 8%; and the content of arsenic in yellow phosphorus can be decreased by approximate 30%.

Description

technical field [0001] The invention relates to a processing technology of yellow phosphorus ore, which belongs to the technical field of chemical industry. Background technique [0002] At present, the phosphate rock used in the production of yellow phosphorus is only put into production after simple processing. Undesirable impurities in phosphate rock, such as carbonate, crystal water, arsenic, etc. affect the production cost and production efficiency of yellow phosphorus. The more impurities, the greater the loss on ignition, the lower the output of yellow phosphorus, and the greater the energy consumption in the process. Therefore, for the yellow phosphorite ore with a large loss on ignition, a method that can remove impurities, Processing methods that reduce energy consumption are of great significance. Contents of the invention [0003] The object of the present invention is to solve the problems of high energy consumption and low output in yellow phosphorus produc...
