[0013] The preparation method of the iron sintered ore sample for observing mineral phase adopts the following process:
[0014] (1) The iron sintered ore is made into iron sintered ore particles with a particle size of 10-12.5mm.
[0015] (2) Use scotch tape to make several paper barrels with a height of 70mm and an inner diameter of 27mm (the number is determined according to the number of tests), one side is sealed and the other side is open, and the open side is flushed up and placed on a small tray.
[0016] (3) Put iron sinter particles into each paper drum, put about 2 / 3 for later use, do not overfill.
[0017] (4) Do a good job of protection in accordance with the requirements for the use of ethylenediamine. First pour epoxy resin into the container, then pour ethylenediamine, the volume ratio of the two is controlled at 4.5-5:1, after pouring in the reagent, stir continuously with a glass rod, a certain amount of smoke will come out during this process , continue to...
Embodiment 1
[0020] Embodiment 1: The preparation method of the iron sintered ore sample for mineral phase observation adopts the following specific process.
[0021] Add a mixed reagent of epoxy resin and ethylenediamine to the iron sinter particles with a particle size of 10-12.5mm, epoxy resin:ethylenediamine=5:1 (volume); then vacuum dry at 70°C for 32min. Obtain the iron sintered ore sample. After the sample is cut, roughly ground and finely polished, it can be used for mineral phase microscope observation.
[0022] This sample was cut by a cutting machine, and after rough grinding and fine polishing, it was found that the sample was mounted very firmly, so the flatness of the sample was very high after grinding and polishing. After many tests with a reflection test microscope, it was found that it was very clear , It has not been found that there is no movement of broken samples, and the performance is stable, which is better than other methods to make samples.
Embodiment 2
[0023] Embodiment 2: The preparation method of the iron sintered ore sample for mineral phase observation adopts the following specific process.
[0024] Add a mixed reagent of epoxy resin and ethylenediamine to iron sinter particles with a particle size of 10-12.5mm, epoxy resin:ethylenediamine=4.5:1 (volume); then vacuum dry at 60°C for 30 minutes Obtain the iron sintered ore sample. After the sample is cut, roughly ground and finely polished, it can be used for mineral phase microscope observation.
[0025] This sample was cut by a cutting machine, and after rough grinding and fine polishing, it was found that the sample was mounted very firmly, so the flatness of the sample was very high after grinding and polishing. After many tests with a reflection test microscope, it was found that it was very clear , It has not been found that there is no movement of broken samples, and the performance is stable, which is better than other methods to make samples.
