Method, system and device for determining hydrophilicity and hydrophobicity of metal sulfide ore and storage medium

Abstract

The invention relates to a method, a system and a device for determining hydrophilicity and hydrophobicity of a metal sulfide ore and a computer readable storage medium. The method comprises the following steps: constructing a unit cell model of the ore according to lattice parameters of the ore, cutting a crystal face on the unit cell model, constructing a corresponding crystal face model according to the crystal face, and constructing a supercell model according to the crystal face model; constructing a water molecule model according to the supercell model, obtaining a water-mineral crystal face model according to the supercell model and the water molecule model, and performing dynamic calculation on the water-mineral crystal face model to obtain a final balance model; and performing energy calculation on the supercell model, the water molecule model and the final equilibrium model to obtain corresponding energy, obtaining adsorption energy of a reaction between a mineral crystal face and water molecules on a unit area according to the corresponding energy, and determining the hydrophilicity and hydrophobicity of the mineral according to the adsorption energy. According to the method, the actual effect between water and the mineral can be truly reflected, so that the hydrophilic-hydrophobic property of the mineral can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of metal sulfide ores, in particular to a method, system, device and computer-readable storage medium for determining the hydrophilicity and hydrophobicity of metal sulfide ores. Background technique [0002] Metal sulfide ores are an important class of metal-occurring minerals. Metals such as copper, lead, zinc, nickel, and molybdenum mostly exist in the form of sulfide ores. For example, 70% of the world's copper resources are in chalcopyrite, and 86% Nickel resources occur in nickel sulfide ore, and 99% of metal molybdenum is produced from molybdenite. Since metal sulfide ores are often associated with impurity minerals such as pyrite, quartz, and feldspar, it is usually necessary to selectively enrich the target minerals by flotation. The flotation operation uses the difference in floatability between minerals for selective separation. Therefore, mineral hydrophilicity and hydrophobicity become crucial...
