3.3.1 Density Determination
3.3.1.1 Use a long-necked funnel to add anhydrous kerosene to a dry, clean Leather density bottle to the neck position of 0.5 ml, then use filter paper to wipe off the kerosene spillage on the neck, plug the bottle and put the density bottle into the super thermostat so that the meniscus of the kerosene on the neck is at hand level. Adjust the temperature to about 10°C higher than the room temperature. The temperature change of the thermostat should be controlled within 0.1°C. After 1 hour of constant temperature, read the initial reading of the kerosene when the Leather density bottle is immersed in the thermostat. Or take out the density bottle from the thermostat and read the initial reading of the kerosene within 5 seconds (V.), (read accurately to 0.05 ml).
3.3.1.2 Weigh 90g (weigh to 0.05g) of the sample that has been cooled after being heated at 105 ± 3℃ for 2h, and add it to the Lea density bottle; cover the bottle cap, gently stamp, roll or manipulate the density bottle to expel the air as much as possible (or use an ultrasonic oscillator to exhaust bubbles for 30min), put the density bottle back into the thermostat, and keep the temperature constant for 30min.
3.3.1.3 Take out the density bottle, gently roll or shake the density bottle again to expel the remaining air (or use an ultrasonic oscillator to exhaust air for 30min), and then put the density bottle into the thermostat and keep the temperature constant for at least 1h. 3.3.1.4 Read the final reading of kerosene (V1) in the same way as the initial reading of coal slug (accurate to 0.05m1). 3.3.1.5 The density β of iron oxide ore powder is calculated according to formula (1): p

Add the weighed sample to 350ml of water containing 0.2% sodium polyphosphate, stir evenly with a glass rod, and then transfer all the suspension into a square hole sieve with a side length of 0.073mm (200 days).
3.3.2.3 Place the sieve on the water sieve seat L and rinse it for 3min with water at a pressure of 69kPa sprayed from the wet sieve nozzle. When rinsing, the nozzle should be close to the sieve and the iron oxide ore powder attached to the sieve frame should be flushed onto the sieve. 3.3.2.4 Rinse the sieve residue twice with distilled water, then transfer all the sieve residue to an evaporating dish of known mass (weighed to 0.01g) (m), place the evaporating dish on a boiling water bath to evaporate the water, then place it in a constant temperature drying oven at 105±3℃ to dry for 2h, take it out and place it in a desiccator to cool to room temperature and weigh it (weighed to 0.01g) (mz). 3.3.2.5 Repeat the determination steps in 3.4.2 using a sieve with a square hole side length of 0.043mm (325 mesh). 3.3.2.6 The sieve residues of 0.073 mm sieve and 0.043 mm sieve shall be calculated according to formula (2) and expressed as percentage.

3.3.5.3 Weigh two samples of iron oxide powder (accurate to 0.1g) baked at 105-3℃ calculated by formula (5) and put them into two porcelain cups. Add 250ml of distilled water to each cup to prepare a 2.50g/cm* iron oxide ore powder distilled water suspension. 3.3.5.4 Stir the suspension with a stirrer for 15min. Stop at least twice during the stirring process and scrape off the iron oxide ore powder adhering to the container wall and the stirring rod blades. Transfer all the stirred suspension into the mud curing tank, let it stand at room temperature, and seal it for curing for 24h. 3.3.5.5 The iron oxide ore powder distilled water suspension that has been airtightly cured is stirred with a stirrer for 15 minutes, and one part of it is measured with a density meter. When the measured density is 2.50±0.02g/cm3, the suspension is transferred to the container of a direct-reading rotary viscometer, stirred with a glass rod, and measured at a rotor speed of 600r/min. Because the iron oxide ore powder in the suspension settles quickly, the reading of the rotary viscometer should be the maximum reading before the reading drops. If the density of the suspension is less than 2.48g/cm2 or greater than 2.52g/cm2, the cause should be found and the measurement should be repeated. 3.3.5.6 Add 2.50g of anhydrous calcium sulfate to another portion of the iron oxide ore powder distilled water suspension (screened with a square hole sieve with a side length of 0.18mm (80 mesh) and place it in a sealed container at room temperature for 30min, then stir it for 15min. Transfer the suspension into the container of a direct-reading rotary viscometer and measure the reading after adding anhydrous calcium sulfate according to 3.7.3.3. 3.3.5.7 Calculate the apparent viscosity of the iron oxide ore powder distilled water suspension before and after adding anhydrous calcium sulfate according to formula (6). 600
