選礦設(shè)備之銅礦選礦浮選工藝與技術(shù)：

目前，我國勘探和開采的銅或銅多金屬礦床，大部分銅礦石都要經(jīng)過選礦富集成銅精礦才能冶煉成銅金屬。銅礦選礦方祛主要有浮選、磁選、重選等方法或濕法冶煉等。為正確選用各種選礦方法和合理制定選礦工藝流程。需要事先研究礦床物質(zhì)成分，查明礦石自然類型，鑒定礦石物質(zhì)組成、結(jié)構(gòu)構(gòu)造、嵌布粒度和礦物可選性能以及有益有害元素賦存狀態(tài)等。

Flotation process and technology of copper ore dressing in mineral processing equipment:
At present, China's exploration and exploitation of copper or copper polymetallic ore deposits, most of the copper ore have to go through the ore dressing rich copper concentrate can be smelting into copper metal. The main method of copper ore dressing flotation, magnetic separation, gravity or wet methods such as smelting. In order to select all kinds of ore dressing method and reasonable development process flow. Need to study the material composition of the ore, find out the ore natural type, identify the ore material composition, structure structure, block size and mineral optional properties and beneficial to the occurrence of harmful elements.
