Process Introduction The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for the upgrading of low sulfide …
In 2019, Xinhai Mining undertook the Laos 2000tpd gold processing project and helping Laos mining industry development. One. Project Background. With the increase of mining depth, the ore characteristic changes a lot. The intrinsical flotation technology flow is not suitable for the valuable elements of recycling.
The operation of this project marks the most significant milestone in Sepon's transition from a copper focussed operation to a gold focussed operation. LXML Sepon suspended gold operations in December 2013 due to declining gold reserves and a low gold price. This reduced the government's revenue as mining is one of Laos' main sources of ...
Also amenable to flotation are fine coal and other minerals such as fluorspar, glass sand, barite, pyrite, talc, and iron oxide. In theory, flotation can be employed for the separation of any slurry containing particles that are sufficiently liberated. Particles ranging in size from 0.5mm down to a few microns are responsive to flotation.
From its beginnings in the first decade of this century, flotation has gradually moved to a predominant role in mineral separation. Alain Kabemba, flotation process specialist at Delkor notes the major trend to treating lower- grade and more finely disseminated ores and lately the re-treatment of tailings.
In 2020, China's Chifeng Jilong Gold Mining started processing oxide gold ore from the Sepon mine in Laos, operated by subsidiary LXML. This marked the first time the project had produced gold in over six years after …
The Selinsing Gold Sulphide Flotation Plant. Monument constructed a new sulphide processing plant at the Selinsing Gold Mine with a designed capacity of 950,000tpa that consists of rougher and cleaner flotation, concentrate thickener, water recovery thickener, reagents storage and mixing and concentrate filtration.
In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. Mining companies are investing in advanced sensors, data integration, and machine learning to gain deeper insights into their flotation …
With declining availability of the rich, easy to process ore bodies by using hand sorting, sizing and gravity circuits, development and adoption of flotation has allowed the mining industry to supply great amounts of valuable metals and metals required by industry and our societies.

Due to the limitation of freshwater sources and increasingly stringent disposal standards [13, 74, 79], the minerals industry has attempted to increase water use efficiency, reduce freshwater utilization, and minimize water discharge, or seek alternatives to fresh water [57, 59, 78, 84, 101].It is widely accepted that flotation is the most popular mineral processing …
The company further stated that the flotation gold recovery was inconsistent due to the high clay content of freshly mined transition ore and the processing of stockpiled transition ore mixed with oxides, resulting in poor flotation response. However, daily recoveries were more than 80% but the overall gold recovery was 61.4% for the 30-day period.

Flotation process is carried out in flotation machines. Under the action of mechanical stirring and aeration of the flotation machine, the ore particles are in a suspended state, which increases the collision chance of the ore particles and the bubbles and disperses the air, so that the ore particles are quickly carried by the bubbles and float to the liquid surface …
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a …
