I. Gold Processing Equipment 1:   Zinc Powder Displacement Device Zinc powder displacement process includes three stages: purification of pregnant solution, deoxidation and displacement filtration. The suspended substance in the gold-bearing pregnant solution is removed by purification stage. The dissolved oxygen in the pregnant solution has an obstructive effect on the gold recovery by zinc displacement, so the oxygen in the pregnant solution must be removed to ensure the smooth progress of gold recovery. The displacement filtration stage includes zinc powder addition and displacement operation. The displacement reaction starts once the zinc powder is added into the pregnant solution. And the final displacement and filtration of gold mud are completed by the displacement device. Therefore,   zinc powder displacement   device mainly includes deoxygenation tower, zinc powder feeder and displacement device. Here are some points we should notice when operate the zinc powder displac

This is a country known as the “geological miracle”, who is rich in mineral resources and is an important resource-based country in West Africa. Guinea has a large variety of mineral resources, large reserves, wide distribution, high mining value and great development potential. In particular, bauxite, iron, gold, diamond, nickel, copper, cobalt and other resources occupy an important position in the world. In recent years, mining companies from around the world have been taking part in mining in guinea. One. Project Background In 2018, Xinhai Mining formally signed the contract of 4000tpd gold mineral processing plant with the client, providing it with one-stop and customized mineral processing EPC+M+O service. Xinhai Mining pointed out that due to the presence of gold particles, some gold particles were lost in the process of sampling, sample preparation and reduction in the original geological exploration process. Therefore, it is necessary to take large samples and the

Gravity separation   method is one of the common methods in   gold recovery , which is to separate the materials by different specific gravity and different settling velocity in the medium. For the arenaceous gold deposit, the gold mostly exists in the form of monomer natural gold, which has large density difference with gangues. Therefore, adopting the gold gravity separation method can obtain good gold recovery effect and economic benefit. There are many kinds of gravity separation methods used for gold recovery, including gravity separation by jigging, gravity separation by shaking table, gravity separation by spiral chute, gravity separation by spiral, gravity separation by centrifugal separator and gravity separation by wind power. Among them, the common gravity separation methods used for gold recovery are gravity separation by jigging, gravity separation by shaking table and gravity separation by spiral chute. 1. Gravity separation by   jigging   used for gold recovery Th

The efficiency of modern mining corporation profit from the leading mineral processing technology, while the leading mineral processing reflected in customized and reasonable processing flow and high-quality mineral processing equipment. The effort of mineral processing efficiency can’t leave the processing technology design and the energy-saving mineral processing equipment. Since its foundation in 1997, Xinhai Mining always pays attention to technology creation. It insists that there isn’t the same mine in the world. Every mine should customized their own mineral processing technology and equipment to create ideal efficiency. In the innovation of equipment, Xinhai Mining Machinery Design Institute has rich mineral machinery design experience and a lot of technics with mineral machinery design experience and mineral processing experience. It holds the tasks of equipment research and development, design, innovation and so on. It has already improved over 80% common mine equipment in
