Claims (1)

Способ разделения минералов по их люминесцентным свойствам, включающий транспортирование потока сепарируемого материала, импульсное облучение этого материала возбуждающим излучением, регистрацию интенсивности сигнала люминесценции минерала, обработку этого сигнала для определения нормированной автокорреляционной функции и сравнение нормированной автокорреляционной функции с заданным значением, отличающийся тем, что в реальном времени регистрируют параллельно интенсивность сигнала люминесценции минерала в нескольких диапазонах значений: с фиксированным коэффициентом усиления и одновременно с N-кратным уменьшением коэффициента усиления, при обнаружении превышения амплитудой сигнала люминесценции заданного значения для определения энергетического вклада люминесценции минерала дальнейшую обработку сигнала для определения нормированной автокорреляционной функции выполняют в диапазоне с N-кратным уменьшением, а также проводят дополнительную обработку сигнала для получения величины отношения интегральной интенсивности люминесценции в конце действия возбуждающего импульса к ее интегральной интенсивности через заданное время после окончания возбуждающего импульса и определения скорости затухания сигнала люминесценции как постоянную времени экспоненты затухания на интервале значений сигнала люминесценции после завершения импульса возбуждения в диапазоне достоверных значений сигнала люминесценции, выделяют полезный минерал из сепарируемого материала в случае, если полученные значения всех определяемых характеристик сигнала люминесценции находятся в предварительно заданном для каждой из них диапазоне.A method for separating minerals according to their luminescent properties, including transporting a stream of separated material, pulse irradiation of this material with exciting radiation, recording the intensity of the mineral luminescence signal, processing this signal to determine the normalized autocorrelation function and comparing the normalized autocorrelation function with a given value, characterized in that in real time register in parallel the intensity of the luminescence signal of the mineral in several ranges x values: with a fixed gain and simultaneously with an N-fold decrease in the gain, if it is detected that the amplitude of the luminescence signal exceeds a predetermined value to determine the energy contribution of mineral luminescence, further signal processing to determine the normalized autocorrelation function is performed in the range with N-fold decrease, and carry out additional signal processing to obtain the ratio of the integrated luminescence intensity at the end of the action of the quenching pulse to its integral intensity after a specified time after the end of the exciting pulse and determining the decay rate of the luminescence signal as the time constant of the decay exponent in the interval of the luminescence signal after the completion of the excitation pulse in the range of reliable values of the luminescence signal, a useful mineral is extracted from the separated material if the obtained values of all the determined characteristics of the luminescence signal are in a predetermined azhdoy of these ranges.
