Spiral classifier   plays a significant role in various mineral processing equipment. It can be said that spiral classifier is an indispensable part of the mineral processing. Here we introduce three factors that influence the working efficiency of the spiral classifier. Ⅰ. Equipment Structure 1. Classifying area size The classifying area size in the tank is the determining factor that affects processing capacity and classifying size. Improving the width of the tank, and increasing the height of overflow weir or decreasing the dip angle can increase the classification area. 2. Overflow weir height. The height of overflow weir affects the sediment size of ore. In the practical operation, Xinhai is adjusted according to the requirement of grinding and the height of overflow weir of the classifier. Ⅱ. Operating Conditions 1.Feeding density Feed density is an important factor for classifying operation. Density not only affects the classification size, but also ...

Recently, a good news came from Colombia 1000tpd copper ore dressing plant. This project has successfully produced the first copper ore with a recovery rate of 87.15%. Colombia is the richest field of green gems in the world. Besides, the main mineral resources includes oil, coal, natural gas, uranium and gold. And the copper production is relatively less, which is mainly exported as by-product of gold. Santiago Angel, President of Columbia Chamber of Mines, said, as the engine for Columbia economic growth, copper had tremendous potential in the next five years, and it was likely to be a new product in the next few years. And he believed that there would be a viable copper project in the coming years. Xinhai always paid close attention to the global mining market, and made lots of research on copper ore in Colombia. During the process of research, the head of Columbia ICER contacted Xinhai and consult some   mineral processing equipment   and processes. In the process...

The distribution of gold mine in China is relatively regular, Shandong Zhaoyuan gold extraction plant is an important mineral processing plant in China. In general, the structure of the gold mine is relatively single, and there are so many differences in types & content of impurities and disseminated particle size, which caused the diversity of gold ore dressing process and equipment. At present, alluvial gold equipment is widely used in various mineral processing plants, and different equipment is selected according to the different types of ores. There are many methods to extract gold, such as physical methods and chemical methods. Physical methods include gravity separation process, which is based on the large proportion of gold ore. The common alluvial gold equipment is   spiral chute ,   jig   and   concentrating table , which is only applied to separate coarser grained gold ore. Because too small gold particles cannot generate obvious stratification un...

Compared to the traditional alloy plate,   rubber liner   of ball mill is more popularized by its unique advantages. Generally, alloy plate has a lot of problems, such as long time-consuming, complicated installation, replacement difficulties, etc., besides, its wearing resistance is not as good as the rubber liner. Finally, rubber liner is widely applied in many mineral processing plants for its small density, easy to processing and strong wear-resisting. However, not all ball mill rubber lining boards are featured with strong wear-resisting performance like Xinhai super wear-resisting rubber liner. As the only one wet natural wear-resisting rubber manufacturer in China, Xinhai makes the content of natural rubber reaches 95%. In addition, Xinhai has passed the appraisal of Xinhai wet rubber production wear-resisting key technology and industrialization from National Technical Committee of Science and Technology, which is about the special liquid nano formulations—room te...

There are a variety of toxic heavy metal ions in   lead-zinc   tailings, these ions often exists in   tailings   as solid form, but with the change of physicochemical properties, the internal toxic ions in tailings will dissolve, which is not good for the recycling of lead-zinc tailings water. Here are several common methods to process lead-zinc tailings water. The ways of processing heavy metals in wastewater mainly include chemical precipitation method, adsorption method, air flotation method, oxidation-reduction method, ion exchange method and membrane separation method. In terms of processing dressing beneficiation wastewater, the most effective measure is that tailings water returns to recycle, followed by purification treatment. Therefore, how to reduce the wastewater discharge (namely how to make good use of wastewater) is the significant point. Here are several common methods to process lead-zinc tailings water: 1. Chemical precipitation method: addi...
