According to the property and composition of the ore, the processing flow of potash feldspar includes the following steps: crushing, washing and desliming, separation, and dewatering process.

Flotation separation is one of the commonly used processing methods in gold ore processing plants. However, in the gold ore flotation process, part of the raw ore has a large mud content, which affects the flotation effect, and may even affect the crushing and concentrate filtering effect. It is recommended to conduct a processing test before determining the process flow and process parameters.

Hematite is a weakly magnetic iron mineral with 70% pure iron content and good flotability. It is one of the main raw materials for iron making. There are many commonly used hematite processing processes, which mainly include gravity separation, flotation separation, magnetic separation, roasting-magnetic separation, and combined separation.

According to the difficulty of separation, gold ore processing can be divided into three levels: easy separation, complex separation and difficult separation. So for these three levels, the following are their processing methods.

​Fluorite is an important non-metallic mineral resource and the main source of fluorine in the industry. There are three kinds of processing processes of fluorite: hand separation, gravity separation and flotation separation. Among them, hand separation and gravity separation are mostly used as auxiliary separation and pre-separation, while flotation separation is the main method.

Chalcopyrite is a widely distributed copper-iron sulfide mineral, often containing trace amounts of gold, silver and other minerals, and is the main copper-containing mineral.

China's potassium feldspar rich resources are few, and often coexist with other impurity minerals, especially a small number of impurities such as iron and titanium, which affect its quality and application, so it needs impurity removal. At present, the main impurity removal methods of potassium feldspar are magnetic separation, flotation separation, acid leaching process and combined process. Specifically, the appropriate impurity removal process should be selected according to the occurrence state of impurity minerals and the embedded particle size.

seven tricks to improve the fluorite flotation index: ensure proper grinding fineness, properly raise the slurry temperature, correct selection of flotation reagents and dosage, maintain proper slurry level, selecting a reasonable slurry pH, pre-softened water and optimize flotation process.

At present, the common tin ore processing processes mainly include gravity separation, flotation and magnetic separation.

The tailings dry discharge is a new tailings processing process gradually emerging at home and abroad, that is, after the tailings slurry is concentrated in multiple stages, and then processed by efficient dewatering equipment such as dewatering vibrating screen to form slag with small water content, easy to precipitate, solidify and be stacked. The slag can be transported to a fixed location for dry storage.

In various kinds of gold ores, the Carlin-type gold ore is a kind of finely disseminated gold deposit mainly produced in carbonate rocks. This gold ore relatively low, the metallogenic scale is large, and the gold particle size is fine.  The main gangue minerals include quartz, calcite, barite, kaolinite, etc., which are difficult to recycle gold mines. The harmful elements such as arsenic and mercury may cause environmental pollution if not handled properly. Next, let’s take a look at the processing difficulties of Carlin-type gold mines and their processing technology.

Hematite, a relatively large mineral resource of weakly magnetic iron ore resources, mainly covers hematite, pseudo-iron ore, specularite, and a small amount of siderite and limonite, etc. Among hematite processing methods, flotation separation is one of the common processing methods. Compared to other processing methods, flotation can effectively extract high-quality iron ore from fine-grained materials, thus providing high-quality raw materials for steel production.
