Abstract

Данное изобретение относится к соединению, получаемому реакционным взаимодействием N-ацилированной нейтральной аминокислоты или ее соли или олигопептида N-ацилированной нейтральной аминокислоты или его соли с моногидроксимонокарбоновой кислотой или ее солью. Соединение имеет структурную формулуЭто соединение применимо в качестве собирателя в процессе для выполнения пенной флотации несульфидных руд, особенно фосфатных руд. Данное изобретение также относится к способу, который включает стадии a) подготовки пульпы фосфатной руды, где руда содержит минерал фосфата кальция или смесь таких минералов и пустую породу, с применением эффективного количества реагента-собирателя для минерала фосфата кальция, который является вышеуказанным соединением, и необязательно других добавок для флотации, b) выполнения процесса пенной флотации, чтобы извлечь минерал(ы) фосфата кальция.
