What is the mining sequence for the cemented backfill mining method?

21.Oct.2026 KZ Editor

The cemented backfilling method is a mining technique in which waste rock or tailings generated during extraction are mixed with cement or other binding materials and then backfilled into underground goafs. This method not only effectively supports the goafs and prevents ground subsidence, but also reduces the environmental impact of tailings disposal.

How to Separate Copper and Zinc Minerals in Polymetallic Ore？

11.Oct.2026 KZ Editor

The core principle of copper-zinc separation is priority inhibition and staged flotation. The whole process adopts the technological route of floating copper first and suppressing zinc, then floating zinc from tailings.

Efficient Purification Technology of Low-Grade Phosphate Rock

10.Oct.2026 KZ Editor

Phosphate ore is an essential strategic mineral for chemical industry, agricultural fertilizer and new energy materials. Natural phosphate rock is often associated with quartz, clay, dolomite and other impurities, resulting in low raw ore grade and high impurity content.

How to Choose Beneficiation Flow for Different Tungsten Ores？

10.Oct.2026 KZ Editor

Tungsten ore resources are mainly divided into scheelite and wolframite, which differ greatly in physical properties, mineral embedding characteristics and beneficiation adaptability. Accurate identification of ore types and targeted process selection are the core keys to improving tungsten concentrate grade and recovery rate.

Impurities in Gold Ore: Types and Removal Methods

26.Sep.2026 KZ Editor

Gold ore typically contains more than just gold. In addition to the target metal, the ore also contains gangue minerals and impurity elements that often interfere with the recovery process or reduce the grade of the final product. Identifying which impurities are present and their form of occurrence is the first step in determining how to treat them.

Common Manganese Ore Beneficiation Processes

25.Sep.2026 KZ Editor

Manganese ore presents a specific set of difficulties. Most manganese deposits are low grade, and much of the ore is finely or very finely disseminated, with a substantial proportion carrying high phosphorus, high iron, or associated valuable metals. Beneficiation is therefore hard.
