The ore type included gold oxidized ore and sulphide ore. The average grade of Au in the oxidized ore was 2.5g/t; The average grade of Au in the suphide ore was 3.39g/t, the average grade of Ag was 40.75g/t. ...
As the exploration got deeper, the original 300tpd silver cyanide plant was no longer able to meet the process needs. Due to the shortage of equipment maintenance and the inappropriate process, the plant capacity fell short of expectations and silver recovery dropped year by year. So the client decided to upgrade the plant. The raw ore consisted of metallic minerals (native silver, pyrite and limonite) and gangue minerals (quartz, feldspar and clay), with silver being the valuable mineral. ...
According to the site data provided by the client, Xinhai Mining EPC supplied this project with Turn-key Solution for Mineral Processing Plant (EPC+M+O). The scope of design work contained: the gold ore heavy separation, the construction drawing design of cyanide mining processing plant (including tailings pond ), including the design of the production workshop of the processing plant, involving water supply and drainage, electricity, civil construction, general drawing and other specialties. The powder ore contained 0.26% copper, 3.1g/t gold, 43.41% iron and low content of other elements. The core ore contained 0.90 g/t gold, 25.45% iron, and low content of other elements. The gold was the mainly recovered elements. ...
The raw ore was gold tailings with an Au grade of 4.7g/t which were fine and required no crushing. ...
In recent years, the new energy market has risen rapidly, and the development momentum of lithium mines is booming. At the beginning of the year, Sinomine Resources Group Co., Ltd. acquired Bikita lithium mine in Zimbabwe for 1.146 billion yuan, which attracted great attention from the market.At the beginning of June 2022, Xinhai successfully signed a 2 million TPA lithium project in Zimbabwe with Sinomine to help its overseas lithium mine construction! ...
The deposit consisted of auriferous quartz veins. Xinhai offered tailored solutions to the project, and crude ingots were produced as final products after smelting. ...
The raw ore had an Au grade of 5.75g/t, a true density of 2.62t/m3 and a bulk density of 1.32t/m3, with gold being the major valuable mineral. ...
The disseminated gold grain size of the raw ore was extremely fine (monomer gold ≤30%; most gold particles ＜13μm) so that single gravity concentration is unable to recover such gold. To identify efficient and sound processes, Xinhai undertook the project of upgrading the original gravity concentration plant. ...
The Tanzania 1,200t/d gold mineral processing plant was an EPC+M+O project. The ore consisted of sulfide (10.7g/t) and oxide (2.4g/t), with Au being the only valuable element. They achieved a leaching rate of 93.75% and 91.58% respectively through the all-slime cyanidation gold extraction process. ...
The Zimbabwe 700t/d gold mineral processing plant was an EPC+M+O project. The raw ore had a gold grade of up to 6g/t. Xinhai worked to ensure environmental protection and workplace safety, optimize plant layout, and shorten construction duration. ...
The Sudan 700t/d gold mineral processing plant was an EPC+M+O project. The ore of this project contained 2.97g/t of gold, most of which were earthy minerals with particle size below 2mm. A small part of the ore was blocky minerals, and the maximum particle size was 70mm. ...
The Malaysia 700t/d gold mineral processing plant was a symbol of Chine-Malaysia cooperation in the mining industry under the policy of “The Belt and Road”. The raw ore consisted of pyrite, quartz, calcite and mica, with gold being the valuable mineral. It had a gold grade of 4.70g/t, silver grade of 4.63g/t, iron grade of 20.10% and a sulfur grade of 20.55%. ...
The Guinea 6,000t/d gold mineral processing plant was an EPC+M+O project. The design scope covered construction drawings and workshop drawings and involved engineers in the fields of mineral processing, water supply, and drainage, power, civil engineering, and general layout. ...
The Mongolia 1,000t/d gold mineral processing plant was an EPC+M+O project. Xinhai worked to achieve high recovery of gold and other valuable minerals by cutting costs and maximizing benefits and attach great importance to workers’ safety, environmental protection and energy conservation. ...
For Vietnam SSG120tpd gold flotation project, Xinhai designed the flotation process according to its ore characteristics, beneficiation plant scale and beneficiation conditions.This project is a mining industry service project undertaken by Xinhai, involving beneficiation test, mine design, equipment manufacturing, packaging and shipping, installation and debugging and other links. ...
