In-depth Analysis: A Classic Renovation Case of 300t/d Gold Flotation Plant in Yunnan

 Many old gold processing plants encounter low recovery rate and unstable production after long-term operation, and unreasonable flotation technology is one of the main reasons. The 300 tons per day gold mine project in Yunnan is a typical and valuable renovation case in the field of gold flotation.

The raw ore of this mine is mainly composed of pyrite, with extremely fine gold grains closely symbiosed with metal sulfide minerals. The original production adopted the combined flow of one roughing, two cleaning and two scavenging. However, due to surface oxidation of arsenic and antimony minerals in the ore, a large amount of flotation reagents were adsorbed, leading to poor overall flotation effect. Faced with this dilemma, the mine cooperated with professional teams to carry out comprehensive process renovation.
The core renovation scheme replaced the original cyclone tailings treatment with staged grinding and flotation, adjusted the quantity of flotation equipment and optimized the reagent application rules. After the upgrade, the production indicators were significantly improved. Before renovation, the gold recovery rate was only 81.80%, while it rose to 90.62% after optimization. The gold grade of tailings dropped from 0.68g/t to 0.34g/t, which means fewer gold resources are wasted.
The upgraded staged grinding and flotation process is not only easier for workers to operate, but also realizes early recovery of valuable minerals from high-impurity ore. It optimizes the slurry separation environment and guarantees long-term stable operation.

Technological Process Analysis of All-slime Cyanidation Applied in Tanzania Gold Processing Project

Gold extraction technology determines the final recovery benefit of mineral resources, and matching targeted technological flow according to actual ore condition is the core premise of stable mine production. The 1200t/d gold processing plant project in Tanzania takes mixed sulfide and oxide gold ore as processing objects, and selects all-slime cyanidation gold extraction technology as the core separation method. With the coordinated operation of crushing, grinding classification, cyanidation separation and tailings treatment processes, the project achieves ideal gold leaching effect, and the complete technological design provides valuable reference experience for similar mixed gold ore processing mines. As an overseas EPC+M+O overall contracting project, this gold plant undertakes the daily processing task of 1200 tons of raw ore. The complex ore composition is the biggest difficulty faced by process design. The mining area ore is mixed with sulfide ore and oxide ore, with respective...

The All-Slime Cyanidation Advantage: Delivering High Recovery at the Tanzania 1200t/d Gold Plant

图片
  For gold mining projects, the choice of extraction process can make all the difference in recovery rates and operational efficiency. At the Tanzania 1,200t/d gold mineral processing plant, Xinhai Mining’s team chose the all-slime cyanidation process—and the results speak for themselves. This proven technology allowed the plant to achieve exceptional leaching rates, even with mixed sulfide and oxide ore compositions. The all-slime cyanidation process works by leaching gold from finely ground ore into a cyanide solution, where the gold is then adsorbed onto activated carbon. The gold-bearing carbon is then sent to a desorption electrolysis system, where pure gold is extracted and later smelted into gold slime. This method is particularly effective for ores with both sulfide and oxide components, as it delivers consistent recovery rates across different ore types. At the Tanzania plant, the process was tailored to the specific characteristics of the ore body: For sulfide ore (10...

From Crushing to Tailings: A Step-by-Step Look at the Tanzania 1200t/d Gold Plant’s Processing Flow

图片
  A mining plant is only as strong as its weakest link—and at the Tanzania 1,200t/d gold mineral processing plant, every link in the processing flow was designed to work in harmony. From the initial crushing stage to the final tailings treatment, Xinhai Mining’s team engineered a seamless flow that maximized gold recovery while maintaining operational efficiency. Let’s break down each stage of this successful plant. Stage 1: Crushing – Setting the Foundation for Efficient Processing The processing journey begins with the crushing stage, where the ore is reduced to a manageable size. At the Tanzania plant, a single open-circuit crushing process was implemented. This system uses primary and secondary crushers to break down the raw ore into particles small enough for the grinding stage. Open-circuit crushing was chosen for its simplicity and reliability, ideal for the site’s operational needs. The result? Consistent particle size distribution, ready for the next step in the flow.
