In the flotation technology, it is necessary to consider not only the selection of flotation agent, dosage, dosing time, but also the charging capacity, pulp concentration, PH value and other issues. In order to determine the appropriate flotation process flow, equipment and reagent before the formal production, improve the field production indicators, improve the mineral recovery rate, and reduce the processing cost, the flotation experiment needs to be carried out. Flotation test mainly includes three steps:
The common froth flotation process of sulfide ore mainly includes priority froth flotation process, mixed froth flotation process, iso-flotation process, differential branching flotation process and potential-controlled flotation process.
Gravity separation method is one of the oldest and most common gold mining processes. In the sand gold deposits, the gold usually exists in the form of monomer natural gold, and its particle size is generally more than 16t/m3, which has a big difference with gangue density, so gravity separation method is the most effective and economic gold mining process.
As the common mineral processing process, the froth flotation process is widely used in the concentrator. Because the froth flotation process is strict with grinding fineness, pulp density, flotation reagent, the flotation plant operators must inspect the flotation conditions during the operation of flotation machine. Here are some common problems of froth flotation process and their and solutions.
As we all know, mineral processing operation consists with three stages, before processing, during processing, and after processing. The prepare before processing mainly includes crushing and screening, grinding and classification, hand sorting and washing. Among them, grinding and classification is an important process as the follow-up process of crushing and screening.
The common purification methods of kaolin mineral include gravity separation, magnetic separation, flotation, chemical treatment, etc. The following are the common purification methods of kaolin mineral.
There are two types of grinding way, open-circuit grinding and closed-circuit grinding. What are the specifics of these two grinding ways? Which grinding way can realize the high-efficiency utilization and improve production rate? In later paragraphs, we will answer these questions.
Lead-zinc ore is a kind of refractory ore among many minerals. Generally speaking, lead-zinc is more poor ores than rich ores, and the associated components are more complex.
Fluorite is one of the common non-metal minerals, also called fluor. The main component of fluorite is CaF2, so fluorite is the industry resource of F. Fluorite has a rich color, usually grows with scheelite, phosphorite, pyrite, blende, quartz, dolomite and other minerals. Flotation separation for the fluorite beneficiation is difficult for similar characteristics between fluorite and pyrite, barite.
Graphite is one of the crystalline minerals of carbon. It has excellent properties such as lubricity, stability, high-temperature resistance and electrical conductivity. With the rise of new energy and new materials industries, graphite has become more and more widely used as an important non-metal.
Due to the complex mineral composition of lead-zinc-copper associated silver ore, the symbiotic relationship, embedded properties and oxidation degree of the ores are different, and the effect ofcsilver extraction process is also very different
The required silver extraction process varies from different mineral nature. The mineral extraction method usually used for independent silver ore centering on silver production is the flotation extraction process. While paragenetic and associated silver mines often use a single flotation method, flotation-gravity separation method, and flotation-cyanidation method, with flotation being the most important process.
