The gold ore heap leaching process is a mineral processing process with a lower cost than conventional cyanide gold extraction, a simpler process, and quicker results. This process is widely used in mineral processing plants. There are many influencing factors in the process of gold ore heap leaching. In actual production, it can only be blamed that if it is not controlled well, it will directly lead to a decline in the beneficiation index and affect economic benefits. The following will introduce ten factors that affect the gold ore heap leaching process.
With the gradual depletion of single-type barite mines, barite minerals associated with other metal ores and non-metallic minerals have become the focus of barite development. The associated components of these barite minerals are complex and closely related. It is also more complicated. This article will take you to understand the common barite beneficiation processing technology.
Recently, the Zimbabwe 2 Million TPA Spodumene Ore Processing Project undertaken by Xinhai Mining has successfully entered the stage of trial production, which took only one year. Xinhai Mining signed a contract with Sinomine Resources in June 2022. This project is the "Turn-key Service for Mineral Processing Plant (EPC+M+O)" project undertaken by Xinhai Mining, providing research and design, and complete equipment manufacturing and procurement, commissioning and delivery, mine management and operation and other services.
Flotation process is the common copper ore dressing method. This paper will introduce the copper flotation process of a copper ore dressing plant in Shanxi province.
China is a major nation of mining production and consumption in the world. Many provinces and cities possess high-quality lead-zinc mine in China, however, due to the unreasonable utilization, the large number of lead-zinc tailings are piled up for a long time, which takes up a lot of lands.

Protecting water resources, preventing water pollution and improving water environment ecology are important parts of environmental protection and sustainable development.
Most non - ferrous metals are metal sulfides ores, such as lead-zinc ore, copper sulfide, which often coexist with a large number of pyrites. Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead-zinc tailings recovery.
Copper ore refers to the mineral aggregate with a certain content of copper ore and can be recycled at the present stage. In general, copper ore is occurred in ore inside as sulfide, and associated with a certain amount of lead and zinc ore.
The common copper sulfide minerals mainly include chalcocite, covellite, bornite, copper pyrites and tennantite, and their inherent floatability decrease in turn. Copper sulfide ore has better floatability than sphalerite, pyrite and other sulphide, so it is more likely to float from the pulp by adsorpting collecting agent.
Copper ore is a kind of high-grade sandy copper ore concentrate. It is widely used in casting, forging, metallurgy, paving, heat treatment, steel structure, space truss structure, ships, bridges, mines and so on
Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".
Molybdenum is widely used in steel, mechanical, electron and aerospace for its high melting point and good solidity. Molybdenum has a low grade of raw material (often is 0.01~0.4%), while high grade is demand in melting, so crushing is necessary.
The residence time in of hematite ore slurry in the flotation cell, reagent system and the adhesion process of bubble-particle. The article is going to introduce the effect of slurry concentration on mining hematite ore.
Nowadays, we have an increased demand for phosphate, and with the exploration of the phosphate-rich ore, there is less rich ore and more poor ore, it pushes the research and development of mining equipment and technology.
