One Article to Help You Know Better about The Processing Flow of Potash Feldspar

2021-02-19 XinHai Views (33)

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.

The High Mud Content of The Raw Ore Affects The Flotation Effect of Gold Ore? Check It Now!

2021-02-15 XinHai Views (178)

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.

Commonly Used Processing Processes of Hematite

2021-02-12 XinHai Views (109)

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.

The Gold Ore Processing Methods According to The Difficulty of Separation

2021-02-08 XinHai Views (136)

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.

Here Are All flotation Separation Processes for Different Types of Fluorite Ore

2021-02-04 XinHai Views (112)

​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.

Four Major Flotation Separation Processes to Separate Chalcopyrite Reasonably!

2021-02-01 XinHai Views (112)

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.

These Processes Can Remove Impurities from Potassium Feldspar

2021-01-25 XinHai Views (212)

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.

Five Tailings Dry Discharge Processes, Which One Is Right for You?

2020-12-18 XinHai Views (211)

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.

Break Through Carlin-type Gold Mineral Processing Difficulties, Help You Grasp The Carlin-type Gold Mineral Processing Technology!

2020-12-11 XinHai Views (195)

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.

Common Hematite Flotation Methods and Introduction of Reagents

2020-11-20 XinHai Views (182)

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.
