The embodiment provides a method for quantitatively evaluating tailings sedimentation performance, which comprises the following steps:
A. pouring the tail mortar into a material containing barrel of a rheometer, and recording the torque of the rheometer when the rotating speed in the tail mortar is constant;
B. establishing a corresponding relation between the measured torque and the time, and drawing a torque and time scatter diagram;
C. fitting the torque and the time dispersion points in the step B by adopting a tailing sedimentation performance fitting function, and solving the numerical value of the parameter in the tailing sedimentation performance fitting function;
D. calculating data corresponding to the tailing sedimentation rate and the time one to one according to the numerical value of the parameter in the tailing sedimentation performance fitting function and the tailing sedimentation rate function;
E. and drawing a scatter diagram of the tailing sedimentation rate and time, and fitting the scatter diagram by adopting the tailing sedimentation rate function.
Compared with the traditional static settlement experiment method implemented by using a measuring cylinder, the quantitative evaluation method for the tailing settlement performance provided by the embodiment can realize the high-frequency automatic data acquisition function in the tailing static settlement experiment process by means of the rheometer, has the characteristics of high efficiency and high accuracy, can quantitatively evaluate the tailing static settlement performance, and can more comprehensively present the characteristic of the tailing static settlement performance.
In the step A, when the tail mortar is not in contact with the rheometer rotor, the collected torque value is zero along with the increase of time; when a rheometer rotor is in tailing slurry for measurement and tailing slurry is in a sedimentation process, the collected torque value is positive and continuously increased along with the increase of time, but the increase rate of the torque value is gradually reduced; when a rheometer rotor is measured in tailing slurry and the tailing slurry finishes a sedimentation process, the collected torque value is positive and remains unchanged along with the increase of time, and the torque value reaches the maximum value of the torque in the whole tailing slurry static sedimentation test; when the rotating speed is reduced to zero from a constant value after the test is finished, the torque value is continuously reduced, and the torque value is finally reduced to zero along with the reduction of the rotating speed to zero.
It can be understood that the constant rotation speed of the rheometer in the tail mortar shows that the rotation speed oscillates back and forth in a very small range, and specifically, the oscillation range can be 0.98-1.02 times of the set rotation speed.
In the step a, the tailing slurry may include tailing and water, and a flocculant may or may not be added. In order to ensure the accuracy of the evaluation result, the stirring piece in the rheometer is close to the bottom of the material containing barrel in the rheometer as much as possible. In some embodiments, the distance between the stirring piece in the rheometer and the bottom of the charging barrel is not less than the maximum particle size of the tailings and not more than 5 times the maximum particle size of the tailings. Specifically, the grain size of the tailings may be 1 time, 2 times, 3 times, 4 times or 5 times of the maximum grain size of the tailings, and generally, the maximum grain size of the tailings is less than 1mm. The distance between the stirring element and the bottom of the cartridge is therefore preferably 1-3mm, for example 1mm, 2mm or 3mm.
In addition, in the step A, the rotating speed of the rheometer in the tail mortar is constant for 1/6h-3h, and specifically can be 1/6h, 1/3h, 1/2h, 1h, 2h or 3h, so as to provide sufficient test data.
In the method for quantitatively evaluating the tailing sedimentation performance provided by the embodiment, the fitting function of the tailing sedimentation performance is characterized in that: the function describes a torque versus time monotonically increasing function and presents a horizontal asymptote, with increasing time the torque value gradually approaching the asymptote but failing to pass through the asymptote.
The tailing sedimentation rate function is characterized in that: the function is a derivative function of a tailing sedimentation performance fitting function, the function describes that the relationship between the tailing sedimentation rate and time is a monotone decreasing function, and the tailing sedimentation rate is gradually close to zero but cannot be equal to or less than zero along with the increase of time.
The tailing sedimentation performance fitting function and the tailing sedimentation rate function can be various, and the tailing sedimentation performance fitting function is specifically explained by two embodiments as follows:
the first embodiment is as follows:
in the first embodiment, the fitted function of the tailing sedimentation performance is as follows:
in the formula: t is torque, T is time, T > 0,a 1 And b 1 Fitting parameters of a function for tailings settling properties, and a 1 ＞0，b 1 ＞0。
In the first embodiment, the tailing sedimentation rate function is:
in the formula: v is the tailing sedimentation rate.
In the first embodiment, a linear fitting mode may also be adopted, that is, the torque T and the reciprocal 1/T of the time are linearly fitted, and then the parameter of the tailing settling performance fitting function is solved.
Example two:
in the second embodiment, the fitted function of the tailing sedimentation performance is as follows:
in the formula: t is torque, T is time, a 2 、b 2 、c 2 And k is a parameter of a fitted function of tailings settling properties, and a 2 ＞0，b 2 ＞0，c 2 ＞0，k＞0。
In the second embodiment, the tailing sedimentation rate function is:
in the formula: v is the tailing sedimentation rate.
It should be noted that, two fitting functions of tailings sedimentation performance and two functions of tailings sedimentation rate are specifically listed in the above two embodiments, and if there are other functions different from the above two embodiments but conforming to the description of the functional characteristics of the two embodiments, it is within the protection scope of the present embodiment.
In at least one embodiment, the torque versus time scatter plot, the tailings settling rate versus time scatter plot, the tailings settling performance fitting function, and the tailings settling rate function are collectively evaluated as a tailings static settling performance.
The following describes the method for quantitatively evaluating the settling property of the tailings by using a specific example:
the raw materials used include tailings and water. No flocculant was added. Wherein the density of the used tailings is 3.00g/cm 3 The volume weight is 1.73g/cm 3 Porosity of 42.3%, particle size distribution as shown in FIG. 1。
The tail mortar used comprises the following components in percentage by weight: the concentration of the tailings is 28 percent.
The measurement system adopted is as follows: the time for the rotation speed to rise from 0 to the constant rotation speed is 5s, the constant rotation speed is 9.55rpm, the duration of the constant rotation speed stage is 10min, and the time for the rotation speed to fall from the constant rotation speed to 0 is 5s, which refers to fig. 2.
The relationship between the collected rotating speed and the time in the constant rotating speed section is shown in figure 3. In the rheometer, the constant rotating speed is shown as oscillating back and forth within a tiny range, namely when the actual rotating speed exceeds the set constant rotating speed, the rotating speed of the rheometer automatically reduces; when the actual rotating speed is lower than the set constant rotating speed, the rotating speed of the rheometer automatically increases. The precise rheometer can narrow the rotating speed oscillation range but cannot change the rotating speed oscillation rule.
In the above constant speed phase, the law of the actual speed oscillation determines that the torque changes differently from that described in fig. 4 over time. Fig. 4 reflects the variation trend of the torque, but the collected torque data still has the characteristic of oscillating back and forth around the variation trend of the torque, as shown in fig. 5.
Selecting
Nonlinear fitting was performed using Origin software on the data collected in fig. 5 as a fitted function of tailings settling performance, with the fitting results shown in fig. 6. This process can also be performed using a tool having a non-linear fitting function such as Matlab software.
Calculating parameter b based on the selected tailing sedimentation performance fitting function 1 3.39981;
according to tailing sedimentation rate function
And parameter b 1 And calculating the data of the tailing sedimentation rate v corresponding to the time t one by one according to the acquired data of the time t.
And drawing a tailing sedimentation rate and time relation image according to the calculated data of the time t and the tailing sedimentation rate v, as shown in fig. 7.
A plot of torque versus time scatter (FIG. 6), a plot of tailings settling rate versus time (FIG. 7), a fitted function of tailings settling performance T =0.10089-3.39981/T, and a function of tailings settling rate v =3.39981/T 2 And the results are used as the evaluation results of the static sedimentation performance of the tailings.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
In summary, the method for quantitatively evaluating the tailings sedimentation performance provided by the embodiment has the following advantages:
