The invention provides a method for recycling mica, feldspar and quartz sand from kaolin tailings. The method includes the following steps that the kaolin tailings are subjected to selective milling; then screening is conducted, oversize coarse products are almost flaky pure mica, and undersize products are subjected to hydraulic classification so that fine sand containing mud can be removed; classification settled sand is reselected repeatedly so that heavy minerals can be removed; reselected fine sand is subjected to medium magnet and strong magnet operations and then magnetic separation fine sand can be obtained; the magnetic separation fine sand is subjected to the first segment of flotation, the mica can be separated at first, and a fragmental mica product is obtained; the feldspar is separated from quartz in the second segment of flotation; and finally the mica, feldspar and quartz product can be obtained, and the fine sand and milltailings produced in the beneficiation process can be used for unfiring of new building materials like aerated bricks. By adoption of the method, kaolin tailing resources can be utilized comprehensively and effectively; and moreover, the technological process is simple, energy consumption is low, 'zero' release of solid waste is realized, the policy requirements of environmental protection act can be met, and the economic, social and environmental protection benefits are good.
