Xinhai Froth Flotation Process

In May 2016, Iranian client commissioned Xinhai Mine Research Institute to conduct beneficiation test after collected 50kg samples in the site. After tested the ore properties of sample ore, Xinhai lab concluded that the ore was gold-bearing quartz vein deposit, the metal mineral were pyrite, limonite and natural gold. The ore grade is 5.61g/t.

Xinhai mineral processing plan: After finished the test in July, Xinhai Mine Research Institute carried on the preliminary exploration of its processing conditions. After compared froth flotation process with cyanide leaching process, Xinhaia Mine Research Institute found that the gold recovery rate in froth flotation process was far higher than in cyanide leaching process. Therefore, after consulting with the client, Xinhai decided to adopt two-stage closed circuit crushing, one-stage grinding and single froth flotation process to get the gold concentrate. After the grinding, then one roughing, three scavenging, three concentration, the process got 87.16% recovery rate of gold concentrate.

Selection of Flotation Cell:

According to the beneficiation test and froth flotation process requirements, Iran 300tpd gold froth floatation plant needed the following flotation cell model:

In August 2016, Xinhai sent professional engineers to the site to learn about the mineral resources and construction conditions. Considered its location, mineral characteristics, the project needs to solve the following problems:

Xinhai production plant was producing flotation cell of this project. The flotation cell of this project was finished in Xinhai manufacturing plant, and was prepared for packaging.

After manufactured and purchased the flotation cell, Xinhai installation and commissioning technicians started equipment installation and commissioning.

To help Iranian workers to operate as soon as possible, Xinhai technicians showed on-site training for plant workers, explained equipment operation notes, helped customers quickly establish own technical team, laid foundation for later stable operation.

In Iran 300 tpd gold froth flotation project, the ore grade was 5.61 g/t, gold concentrate grade was 78.85 g/t, flotation recovery rate was as high as 87.16%, the final recovery rate was up to 87.16%,the customers gave high praise for these results. From the beneficiation test, mine design, equipment manufacture, installation and debugging to the worker training and standard reached, Xinhai provided a series of froth flotation process service.
