Description

Известны способы флотационного обогащени  медно-молибденовых руд с получением коллективного медно-молибденового концентрата и применением в цикле флотации хвостов основной или -контрольной флотации компонента, сернистого натри  и углеводородов.Methods are known for the flotation concentration of copper-molybdenum ores with the production of collective copper-molybdenum concentrate and the use of the main or control flotation of the component, sodium sulphide and hydrocarbons in the flotation cycle.

Однако такие способы мало эффективны и не дают высокого извлечени  молибдена.However, such methods are not very effective and do not yield high molybdenum recovery.

Предлагаемый способ отличаетс  от известных тем, что дл  повышени  извлечени  молибдена в медно-молибденовый концентрат в пульпу добавл ют сернистый натрий в количестве 0,3-3 г на 1 кг меди , содержащийс  в 1 т обрабатываемого продукта, осуществл   указанную дозировку одновременно с дозировкой углеводородов с последующим перемешиванием пульпы.The proposed method differs from the known ones in order to increase the recovery of molybdenum, sodium sulphide in an amount of 0.3–3 g per 1 kg of copper contained in 1 t of the processed product is added to the pulp by performing this dosage simultaneously with the dosing of hydrocarbons. with the subsequent mixing of the pulp.

Така  дозировка сернистого натри  обеспечивает временную десорбцию ксантогената, используемую дл  закреплени  керосина на молибдените .Such a dosage of sodium sulfide provides a temporary desorption of xanthate used to fix kerosene to molybdenite.

Опыты показали, что указанную дозировку сернистого натри  можно осуществл ть и перед перефлотацией пенных флотационных медномолибденовых продуктов или леред их добавлением к потоку обрабатываемого материала. При этом повышаетс  выход концентрата.Experiments have shown that the indicated dosage of sodium sulfide can be carried out before re-flotation of foamy flotation copper-molybdenum products or lered by adding them to the material stream. This increases the concentrate yield.

№ 138898 2 в 1 г обрабатываемого продукта, осуществл   указанную дозировку одновременно с дозировкой углеводородов с последующим перемещиванием пульпы.No. 138898 2 in 1 g of the processed product, carried out the specified dosage simultaneously with the dosage of hydrocarbons with the subsequent movement of the pulp.

2. Способ флотации медно-молибденовых руд по п. 1, отличающийс  тем, что дозировку сернистого натри  в указанной норме осуществл ют nepeji. перефлотацией пенных флотационных медно-молибденовых продуктов или перед их добавлением к потоку обрабатываемого материала.2. The method of flotation of copper-molybdenum ores according to claim 1, characterized in that the dosage of sodium sulfide in this standard is carried out by nepeji. by re-flotation of foamy flotation copper-molybdenum products or before adding them to the stream of the processed material.
