Description

technical field [0001] The invention relates to the technical field of mineral processing technology, in particular to an aqueous suspension formed of ore and modified ore particles and a preparation method thereof. Background technique [0002] In many industrial processes, it is necessary to separate precious metals with relatively high value or relatively small precious metals by various methods. In the prior art, flotation or mechanical methods are often used to separate precious metals; flotation It is a mixture of water, valuable materials (such as mineral particles), unwanted materials, chemicals, and air in the flotation cell. The use of chemicals makes the desired materials hydrophobic, while the use of air will have Valuable material is carried to the surface of the flotation cell, but when the hydrophobic material collides with the gas bubbles, they stick to each other and the bubbles rise to the surface carrying the desired material with them, the surface area fl...
