The traditional approach to lead-zinc sulphide flotation involves sequential flotation of lead, zinc, and sulfur. However, achieving optimal results requires careful consideration of several factors, as highlighted by a recent project undertaken by Dasen Mining in Tanzania. The Challenge: Suboptimal Zinc Flotation Last year, Dasen Mining was invited to assess and improve a lead-zinc ore […]

Heap leaching is a widely used method for extracting silver from lead-zinc ores. This article outlines the key steps and considerations for cyanide heap leaching, a process that Dasen Mining has extensive experience with. 1. Site Construction Heap leaching sites are typically located on gentle slopes near mining operations for easy transportation. The site is […]

In the realm of mineral processing, flotation is a vital technique employed to selectively separate minerals based on their surface properties. The effectiveness of flotation hinges on the judicious use of flotation reagents, which can significantly influence the floatability of various minerals. These reagents act by modifying the surface characteristics of minerals, making them either […]

In the dynamic world of sand and gravel aggregate production, industrial conveyors are the backbone of efficient operations. At Dasen Mining, we frequently receive inquiries about the installation and disassembly of belt conveyors, particularly the DTL140/140/4*710S model. This article provides a detailed, step-by-step guide to ensure a seamless installation process, maximizing efficiency and longevity.   Note: dtl140 / 140 / 4 * 710s conveyor is equipped with 3 driving rollers and 4 710KW motors, which are driven by head single point drive. The hydraulic braking device is set at the head and the hydraulic tensioning device is set at the tail. The length of the machine body is […]

As a widely used coarse-breaking equipment, the jaw rock crusher has been around for more than a century. Jaw fractures on the market today differ in their structure, shape, design, and materials. It is mainly introduced from seven perspectives in this paper: crushing cavity, frame, discharge port adjustment, motor installation, and bearing. By analyzing your […]
