Silver-lead concentrate is an intermediate product obtained through beneficiation processes from lead ores containing silver or lead-silver co-occurring ores. It is an important raw material for the smelting of silver and lead. Among this type of minerals, silver mostly exists in the form of natural silver and silver sulfide, while lead is mostly found in galena. In ores with a higher degree of oxidation, it may also exist in the form of cerussite and anglesite. This article will introduce how to separate silver-lead concentrate.

Recently, the Ministry of Natural Resources announced that high-purity quartz sand has officially become the 174th new mineral in my country. It is required that the purity of silicon dioxide after beneficiation and purification of high-purity quartz ore shall not be less than 99.995% (4N5 grade), and the content of impurities and inclusions can meet the stringent requirements of high-tech fields such as semiconductors and photovoltaics. The announcement of this news has injected new vitality into the development of related industries. This article will take this opportunity to introduce the standards of high-purity quartz sand and the beneficiation and purification technology of high-purity quartz sand.

The carbon slurry gold extraction process is to enrich and extract gold by adsorbing gold cyanide complexes in the ore pulp with activated carbon. In the process of gold extraction, the stable operation of the equipment is the basis for ensuring the efficient implementation of the process. Standardizing the maintenance and maintenance of carbon slurry gold extraction equipment will not only help improve gold production efficiency and reduce production costs, but also meet the inevitable requirements of sustainable development of the gold industry.

Fluorite, as an important strategic mineral resource, has extensive applications in fields such as metallurgy, chemical engineering, and new energy. With the gradual depletion of high-quality fluorite resources, how to efficiently develop and utilize low-grade lean ore resources is the key. This article will sort out the classification criteria for poor and rich fluorite ores for everyone, as well as the mineralogical characteristics and chemical composition differences between the two types of ores. It will also summarize the different beneficiation process flows suitable for poor and rich ores in a targeted manner.

Mica is a layered hydrated aluminosilicate mineral containing multiple elements such as potassium, aluminum, magnesium, iron, and lithium. It is widely used in various industrial fields, ranging from an insulating foundation in the electrical and electronic industries to a reinforcing additive in plastics and rubber, and even to a core raw material for pearlescent pigments. Mica is everywhere. With the development of technology and the progress of industry, the demand for mica has been continuously rising. How to efficiently, safely and environmentally friendly mine and select mica ores has become the focus of research in the mining field. This article provides a detailed introduction to mica mining and beneficiation.

Pegmatite feldspar ore is an important source of feldspar resources, and is used in glass, ceramics, abrasives and other industries. With the rapid development of related industries, the demand for high-quality feldspar ore is growing. Therefore, the technical requirements are also constantly updated. Gravity separation, as one of the commonly used technologies for feldspar ore dressing, has the advantages of simple process, low energy consumption and no pollution. This article will focus on the gravity separation of pegmatite feldspar ore.

After a long period of development, the global mining industry has reached an astonishing scale of tailings stockpiles. According to statistics, the cumulative stockpiles of tailings in the world exceed 500 billion tons, and the precious metal resources contained in them are of great value. Taking gold as an example, the average grade of gold in global tailings is about 0.3-0.8g/t. According to the current gold price, the potential economic value exceeds 100 billion US dollars. Therefore, tailings are not waste, but an "invisible mine" that needs to be developed urgently. In addition to gold, what other minerals can be recycled in tailings? This article will mainly focus on the reselection of precious metals in tailings, including methods for reselecting precious metals in tailings and types of reselected precious metals.

Manganese ore is the main raw material of the manganese industry, a commonly used desulfurizer and deoxidizer in the steel industry; a catalyst for the preparation of manganese dioxide in the chemical industry; and a positive electrode material for the production of zinc-manganese dry batteries in the energy field. With the gradual reduction of manganese-rich ores, manganese oxide has gradually become the main development target. Common types of manganese oxide minerals mainly include pyrolusite, pyrolusite and hydromanganese. Let's learn about the beneficiation methods of these three types of manganese oxide ores!
