Tailings Reselection Precious Metal Technology
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 oxide ore: beneficiation methods for pyrolusite, pyrolusite and hydromanganese!
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!...

Common gold placer beneficiation equipment
Primary gold ores exposed to the air undergo weathering, gradually breaking into gold grains and rock debris. Under the transportation of external forces, the heavier particles accumulate on hillsides, riverbeds, and the shores of lakes and beaches. When these sediments have development value, they become placer gold ores. The beneficiation operation of placer gold ore can be divided into preparation operation and separation operation. Here, a brief introduction to the commonly used placer gold ore beneficiation equipment is provided....

Technical Guide for Fluorite Tailings Treatment
Fluorite is a major raw material required in industries such as metallurgy, chemical engineering, and building materials. Fluorite concentrate is obtained by purifying raw stones through mining and is used in various fields. However, the large amount of tailings produced during the fluorite beneficiation process poses challenges to the surrounding environment. Meanwhile, due to the inadequate early technology, some concentrate resources are forced to enter the tailings, resulting in resource waste. According to statistics, the global annual output of fluorite tailings has exceeded 120 million tons. As a major producer of fluorite, China's annual output accounts for 43%. It is very necessary to carry out effective treatment for this type of tailings. This article will introduce the treatment technology of fluorite tailings ponds....

Principles and processes of gold placer re-selection!
This year, the revised Mining Act of Papua New Guinea strictly restricts foreign investment in gold placer mining, allowing only citizens of the country to engage in the industry, while encouraging foreign investment to enter the market through large-scale mining projects. The introduction of this policy has once again pushed gold placer to a fever. In this article, we will focus on gold placer and learn about the process of gold placer beneficiation!...

Fluorite Ore Dressing and Phosphorus Removal Method
As a global strategic non-metallic mineral resource, fluorite is a key raw material in the fluorine chemical industry chain and plays an important role in metallurgy, building materials, new energy, semiconductors and other fields. . As a major fluorite resource country, my country ranks among the top in the world in terms of reserves and output, but a considerable proportion of it is phosphorus-containing fluorite ore. With the continuous improvement of the quality requirements of fluorite products in the industrial field, effective phosphorus removal is very necessary to expand the market application of phosphorus. Let's take a look at the ore characteristics of phosphorus-containing fluorite ore and the effective phosphorus removal method of fluorite ore!...
