Copper-lead-zinc ores are common polymetallic mineral types and important raw materials for the non-ferrous metals industry. Their ore types are complex, often existing as sulfide ores, oxide ores, or mixed ores. Due to the close association of copper, lead, and zinc minerals and their similar floatability, effective separation is quite difficult. This article will introduce copper-lead-zinc ore separation and beneficiation technologies from multiple perspectives.

Mica is a layered hydrous aluminosilicate mineral containing various elements such as potassium, aluminum, magnesium, iron, and lithium. It has applications in many industrial fields, and with technological development and industrial progress, the demand for mica continues to rise. This article provides a detailed introduction to mica ore beneficiation methods!

The mining methods for mica need to be selected based on the deposit type, occurrence state, and ore characteristics. The main mining principle is "protecting the integrity of mica crystals," prioritizing mining methods that minimize ore disturbance. Currently, there are two main categories: open-pit mining and underground mining.

In the gold mining industry, finding low-cost, high-efficiency gold extraction processes has always been a key driver of industry development. With the gradual depletion of high-grade gold ore reserves, the development and utilization of low-grade gold ore (typically referring to gold grades in the range of 0.5~3 g/t), as well as tailings and waste rock, has indeed become a focus of industry attention. Heap leaching gold extraction, with its low cost and high efficiency, provides a feasible path for the effective utilization of low-grade gold ore. Let's explore heap leaching gold extraction technology and the secrets to its low cost and high efficiency.

Recently, the Ministry of Natural Resources officially designated high-purity quartz sand as my country's 174th new mineral resource. The requirements stipulate that after beneficiation and purification, the silica purity of high-purity quartz ore must be no less than 99.995% (4N5 grade), and the impurity and inclusion content must meet the stringent requirements of high-tech fields such as semiconductors and photovoltaics. This announcement has injected new vitality into the development of related industries. This article will introduce the standards for high-purity quartz sand and its beneficiation and purification technologies.

​Manganese ore is a major raw material in the manganese industry, a commonly used desulfurizing and deoxidizing agent in the steel industry; a catalyst for the preparation of manganese dioxide in the chemical industry; and a cathode material for the production of zinc-manganese dry batteries in the energy sector. With the gradual depletion of rich manganese ore, manganese oxide has gradually become a major development target. Common types of manganese oxide minerals mainly include pyrolusite, schist, and manganese ore. Let's learn about the beneficiation methods for these three types of manganese oxide!

Iron ore is an important raw material for industrial production, playing a vital role in driving industrial production. However, due to the depletion of rich iron ore resources, the development of complex and difficult-to-beneficiate iron ore resources has become a focus of industry. These ores exhibit polymetallic coexistence, making individual separation extremely difficult, increasing beneficiation costs, and posing a potential environmental pollution risk. Therefore, it is necessary to conduct in-depth analysis and research on beneficiation processes for different difficult-to-beneficiate iron ores to improve beneficiation indicators and resource utilization rates. This will accelerate the development and utilization of iron ore and promote the economic benefits of beneficiation plants. This article will introduce several low-grade iron ore beneficiation technologies.

This year, Papua New Guinea revised its Mining Act, strictly limiting foreign investment in placer gold mining, allowing only domestic citizens to participate in the industry, while encouraging foreign investment through large-scale mining projects. This policy has once again fueled the placer gold boom. This article will focus on placer gold, introducing the beneficiation process!
