Why Has the Philippine Government Lifted the Ban on Open-Pit Gold Mining?

Mr. Wilfredo Moncano, Director of the Bureau of Minerals and Geosciences of the Philippines, confirmed that Roy Cimatu, Minister of Environment and Natural Resources, has signed an executive order lifting the ban. Now, the doors are open for commencing open – pit gold mines, which is set to reshape the country’s mining landscape. The Philippine […]

How Does the Open-Cut Mining Process Work?

Open-cut mining, also known as open-pit mining, is a method of extracting valuable minerals directly from the Earth’s surface. The large excavations created by this process are commonly referred to as open-pit mines. This method is widely used due to its efficiency and cost-effectiveness in accessing near-surface ore deposits. 1. Classification of Open-Pit Mines Open-pit […]

What Are the Most Efficient Mining Methods for Lead and Zinc Ore?

The lead and zinc mining industry deals with ore of lead and zinc, which is a relatively difficult one to handle. In general, lead-zinc ore in the context of lead and zinc mining is leaner and the associated components are more complex than rich ore. Therefore, in the beneficiation industry within lead and zinc mining […]

Gold heap leaching operation in cold weather

Gold heap leaching operations are highly dependent on the climate and environmental conditions of the mining area. In tropical regions, operations can continue year-round, with the only caveat being the need to avoid the plum rain season to prevent waterlogging, which can adversely affect the leaching process. In subtropical areas, the optimal leaching period typically […]

Which Flotation Techniques Maximize Copper Yield in Oxide Ore Beneficiation?

Cuprite is an oxide mineral characterized by its low hardness, high density, and distinctive red color. It is formed through the weathering of copper sulfide and typically exhibits a high ore grade. The copper flotation process is the most widely used beneficiation technique for cuprite ores. The primary recovery methods include conventional sulfide flotation, hydrothermal […]

Gold Ore Processing Equipment: A Guide to Setting Up Your Gold Mine

The gold mining process is a critical method for extracting this valuable metal, especially as gold continues to appreciate and its applications expand rapidly. Consequently, the intensity of gold mining is also increasing annually. The majority of gold raw materials in today’s market originate from vein gold mines, which account for approximately 75-85% of the […]

How Can You Improve Screw Classifier Efficiency in Mineral Processing?

In the mineral processing industry, many concentrators encounter the issue of significantly reduced classification efficiency in their screw classifiers. The primary cause of this problem is the disordered settling of fine and heavy ore particles alongside coarse and light particles during the classification process. This leads to the phenomenon of “equal fall,” where fine particles […]

Why Are Flotation Reagents Essential for Effective Gold Separation?

The gold flotation process is a cornerstone of modern mineral processing, offering precise control and high efficiency in separating gold and other valuable minerals. This process is highly valued for its ability to effectively utilize flotation reagents, allowing for the selective separation of minerals according to specific requirements and enabling comprehensive resource utilization. The Role […]

Is Tailings Treatment Essential After Gold Froth Flotation?

Gold froth flotation is a cornerstone of modern mineral processing, enabling precise and efficient separation of gold and other valuable minerals. The process is crucial for maximizing flotation gold recovery. It is highly valued for its ability to selectively separate minerals, which is achieved through the effective use of flotation reagents. While flotation reagents play […]

What are the Stages of Gold Smelting?

Gold smelting is a complex and crucial process that transforms raw gold ore into valuable gold bricks. The journey from the discovery of gold – bearing ore to the final product involves multiple intricate stages. First, the exploration phase begins. Gold is often initially detected in regional heavy sand sampling, which helps in preliminarily determining […]
