I. World gold market analysis in 2016 The World Gold Council report stated that market uncertainty and expansionary monetary policy will continue to support gold investment and central bank demand. Combined with the analysis of the previous bull and bear market cycle rules, gold may enter a new bull market. In the first quarter of 2016, gold performed strongly, and the price of gold denominated in US dollars soared by 17%, making it the best performance in the past 30 years. Gold has become the best performing global asset in 2016. Gold mine asset mergers and acquisitions, expansion and expansion of production, cost reduction and efficiency increase are the main themes of the recent market development. Practice has proved that Changjie Gold Mine Filter Press is the first choice for domestic and international gold concentrates, tailings cost reduction and efficiency filtration, and is an advanced and reliable filter press that can completely replace imports. At present, in order to respond to the needs of customers under the new normal mining industry, Changjie Filters vigorously implemented the project of “cost reduction and efficiency increase and benchmarking and tapping potential†and made substantial progress. On the basis of the original CJR, CJZJ, and CJXA, new CJZH, CJAH, etc. were added. More cost-effective high-quality models, and strive to make Changjie filter press to become the first choice for all types of customers around the world.

II. Economic and Technical Comparison of Gold Tailing Filter Press Changjie Gold Mine Filter Press integrates three-stage complete filtration and no-diaphragm pressing in one, compared with domestic box-type diaphragm filter press and frame filter press, with filter cake Low water content, strong adaptability of filtration materials (different elevation, fineness, concentration, etc.), and single processing capacity are significant advantages.
Compared with foreign imported filter presses, Changjie Filter Filter Gold Concentrate filter cake moisture content of at least 10%, a single daily processing capacity of more than 2,000 tons, gold tailings filter cake after the minimum moisture content of 8%, The average daily processing capacity of a single unit exceeds 2,400 tons. In terms of moisture content and processing capacity, Changjie filter press can reach or even surpass international advanced brands. However, Changjie filter press purchase cost and operation and maintenance cost are far lower than imports. Filter press.
Although the vertical filter press has a relatively low moisture content, due to its complex structure and many design flaws such as wearing parts, it is prone to problems such as spraying of the equipment and damage to the filter cloth. The equipment has a long maintenance time and high operation and maintenance costs, and is subject to height restrictions. Etc., vertical filter press production capacity is limited. Changjie filter press can reach or even better than the vertical filter press in terms of water content and processing capacity, but the purchase cost is lower. Especially, Changjie filter press is simple, durable and durable, with few wearing parts, and the cost of operation and maintenance is extremely low. low.
Third, Changjie filter filter gold ore filter case China Gold Baotou Xinda flotation gold tailings using ceramic filter filter, in 2013, the mine will further refine the mineral after expansion. After fine grinding, the ceramic filter cannot be effectively filtered, the cake thickness is reduced to 2mm, the moisture content rises to >15%, and the dry heap cannot be obtained. In order to solve the above problems, the mine uses a water conservancy cyclone, classifies over 400 meshes into ceramic filter, and -400 mesh minerals are filtered with CJXA high energy filter press. After the CJXA high energy filter press is put into use, the -400 mesh 95% gold tailings are filtered and the filter cake moisture content is <11%. The coarse-grained gold tailings that are filtered out by the ceramic filter have a water content of the filter cake of >13%. Successfully achieved dry tailings.
Jilin Laojin Plant leached gold tailings and began using Changjie filter presses in 2006. It has added two units to meet the expansion needs. After filtration, the moisture content of the gold tailings filter cake is 8%, and the tailings can be put into pit stacking, realizing the normal production of tailings dumping and dry dumping. After filtration, the cyanide content of the filter cake directly meets the environmental emission requirements.
Gansu Huixian Hongyuan Mining selected Changjie filter press in 2008 to solve the problem that the moisture content of the filter cake of the original box type diaphragm filter press is high (more than 20%) and the tailing pond cannot be dry heaped. Compared with the same workshop, Changjie filter cake moisture content is only 10%.
Hunan Longxin Mining Hengyang Longwangshan Gold flotation tailings are high-yielding gold minerals and are difficult to filter. After the mine was put into operation, gold tailings were filtered using various equipment such as ceramics, belt filters, and box filter presses. The moisture content of the filter cake was higher than 28%, and the processing capacity was extremely low and the dry heap could not be dried. Later, the mine used CJXA high energy filter press to filter the gold tailings, the moisture content of the filter cake was <16%, and the single processing capacity was >400 tons, which solved the tailings filtration problem of the mine.
The leaching of gold tailings from Jilin Huadian Gold Co., Ltd. requires no thickener and direct direct filtration. The moisture content of the filter cake is relatively low. After comprehensive selection of various filter presses, Changjie CJXA high-energy gold tailings filter press was finally selected to achieve a non-dense period of filtration, with a filter cake moisture content of <10% and a single processing capacity of >300 tons.
Sichuan Xinhe Mining was built near Litang County in Sichuan Province. Above 4000 meters above sea level, it is a rare high-altitude flotation gold ore process. At the beginning of construction, the plant inspected high-altitude concentrators several times. From the consideration of low-concentration, high-altitude and other conditions, Changjie CJXA high-energy gold concentrate filter press and equipment with strong adaptability, low moisture, and durability were selected. After being put into production normally, the moisture content can be controlled below 12%, and a single piece of equipment can process more than 20 tons of gold concentrate on a daily basis, which realizes a period of dewatering of the filter press equipment (without thick equipment), and greatly reduces the investment cost and transportation cost.
The Gansu Zijin Zijin Plant requires that the moisture content of the filter equipment must be less than 11%, and the tender contract also requires strict acceptance of the equipment in accordance with this standard. Changjie CJXA high-energy gold concentrate filter press won the bid. The filter cake moisture content is below 10%, and the processing capacity of a single table is 500 tons. The equipment operates stably, the operation and maintenance is simple, the spare parts consumption is low, and the operating cost is low. Compared with domestic filter presses, millions of expenses can be saved each year.
