Silica sand processing technology is mainly purification, to remove small or trace amount of impurities. It is a difficult separation technology to recover refined silica sand and high purity silica sand.
According to the classification of chemical composition, the common iron ore mainly includes magnetite, hematite, limonite and siderite. Different properties of iron ore, its processing technology is naturally different.
There are multiple mineral impurities in gold ore. The different grades of impurities are closed related to the particle size of gold ore. Therefore, it is necessary to wash and or classify the raw ore.
Flotation is the decisive step in large copper and polymetallic processing plants, where rising capacities and complex ores demand higher recovery, stable operation and lower costs. Xinhai’s K-series large circular flotation machines were engineered to meet these challenges. Featuring optimized tank geometry, dual drive options, precision manufacturing and intelligent control, the K-series delivers predictable, energy-efficient performance on a massive scale—validated by successful deployment in a 3.5 Mt/a copper concentrator in Zambia.
In this article, we highlight five key Xinhai products – ball mills, thickeners, flotation machines, slurry pumps, and hydrocyclones – covering their applicable ores, available configurations, technical advantages, and real-world applications.
Various reasons make the flotation treatment of lead-zinc oxide ore difficult. This article will introduce you to 5 flotation methods and teach you how to choose lead-zinc oxide ore.
Different iron ore tailings re-processing technologies are according to different ore characteristics. The common iron re-processing technologies are single magnetic separation technology, gravity-magnetic separation combined technology, flotation-magnetic separation combined technology, and flotation-magnetic-gravity separation combined technology.
At present, the main impurity removal methods of potassium feldspar are magnetic separation, flotation separation, acid leaching process and combined process. Specifically, the appropriate impurity removal process should be selected according to the occurrence state of impurity minerals and the embedded particle size.
The belt conveyor is a kind of material transportation equipment commonly used in the current concentrator, in which the belt plays an important role as the load bearing and transport device.
Mineral processing plant design is the critical blueprint for turning lab test results into successful industrial production. A scientific, well-structured design helps control costs, reduce risks, improve recovery, and ensure safe, stable, and environmentally compliant operations from construction to long-term production. This key phase directly impacts investment decisions, project efficiency, and operational profitability. Why and how does Xinhai design a mineral processing plant?

In antimony-bearing gold ores, the main target minerals include stibnite, native gold, pyrite, and arsenopyrite. Pyrite and arsenopyrite are the primary gold-bearing minerals, while some stibnites also contain gold, and arsenopyrite and pyrite contain arsenic. Because the gold in antimony-bearing gold ores is finely embedded and the stibnite consumes cyanide and oxygen, flotation is often used for recovery. In production, in addition to the recovery of coarse native gold using gravity separation, the beneficiation of this type of gold ore focuses on the flotation separation of stibnite from pyrite, arsenopyrite, and other minerals, often employing preferential flotation and mixed-preferential flotation. Depending on the specific reagents used, flotation methods for antimony-bearing gold ores can be further divided into sodium hydroxide, sodium sulfide-sodium hydroxide or sodium carbonate, oxidant, and butyl ammonium black powder.
The dry tailings disposal system – also called drained tailings stacking – is a sustainable technology that has been increasingly adopted in modern mining plants. Instead of accumulating slurry in large dams, we aim to concentrate solids and return most of the water to the production process. At Xinhai, we consider this technology essential to promote cleaner, safer and more efficient mining. Below, we will introduce the processes related to dry tailings discharge, the equipment involved and real cases from Xinhai.
Environmental conditions such as climate, water availability, and terrain have a direct impact on the planning and construction of mineral processing and tailings projects. From high temperatures and freezing winters to heavy rainfall and drought, each challenge requires specific engineering solutions. At Xinhai, we integrate these factors into every project we deliver — ensuring safe, efficient, and sustainable results across diverse mining environments. The following sections explore how Xinhai tailors its strategies to address challenges related to climate, water resources, and topography.
