      <abstract xml:lang="ru">
        <p>Уже более четверти века непрестанно говорится об отставании теории флотационного процесса от его практики. Все деятели в области флотации это знают. Однако до сего времени никто из обогатителей не поставил и не попытался решить вопрос о причинах такого недопустимого и вредного положения. Мой доклад имеет целью дать обзор истории развития и состояния вопроса теории флотации за рубежом. Вместе с тем, в конце сообщения я позволю себе в качестве предпосылки к следующему докладу сделать некоторые выводы о путях, которыми должна двигаться отечественная флотационная наука, чтобы подняться на высоту, отвечающую требованиям нашей замечательной эпохи. Не знаю, существует ли более яркий, чем флотация, пример того, как в капиталистическом мире наука делается орудием наживы отдельных мощных финансовых группировок.</p>
      </abstract>
      <abstract xml:lang="en">
        <p>For more than a quarter of a century it has been incessantly said about the lag between the theory of the flotation process and its practice. All figures in the field of flotation know it. However, until now none of the enrichers has put and tried to solve the question about the reasons of such an unacceptable and harmful situation. My report is intended to give an overview of the history of development and the state of the question of the theory of flotation abroad. At the same time, at the end of the report I will allow myself as a prerequisite for the next report to make some conclusions about the ways in which the domestic flotation science should move in order to rise to a height that meets the requirements of our remarkable era. I do not know if there is a more striking example than flotation of the way in which in the capitalist world science is being made an instrument of profit by certain powerful financial groups.</p>
