It refers to <strong>loose gold deposits<\/strong> formed when gold elements are weathered and eroded on the Earth&#8217;s surface, transported by water or glaciers to low-lying areas, and deposited. The core mineralization process can be summarized in three stages: &#8220;source-transport-reservoir.&#8221; The source of the ore is often gold-bearing primary rock (such as quartz vein gold deposits). Through long-term temperature changes, freeze-thaw cycles, and chemical oxidation, gold particles are separated from the parent rock. During transport, the turbulent flow of rivers separates gold from lighter minerals, leading to enrichment in river bends, convex banks, or terraces where the flow slows. Glacial transport, through the grinding and deposition of glacial till, forms glacial till-type placer deposits. Global placer gold production accounts for approximately 10%-15% of total gold production, making it one of the most important sources of gold.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-fe3cb5e elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"fe3cb5e\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-f92614b\" data-id=\"f92614b\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3c30771 elementor-widget elementor-widget-heading\" data-id=\"3c30771\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Caract\u00e9ristiques principales<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0d0266f elementor-widget elementor-widget-text-editor\" data-id=\"0d0266f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Particle characteristics of placer gold deposits include: particle size mostly between 0.1-2 mm, shape varying from <strong>round to irregularly angular<\/strong> depending on transport distance, and surface often covered with a thin film of iron-manganese oxides. Since placer gold particles are not chemically bonded to gangue minerals, they coexist only through physical adsorption or mechanical mixing. They can be directly separated without crushing or grinding, significantly reducing beneficiation costs. Therefore, placer gold is <strong>easily liberated<\/strong>, but the presence of these associated minerals increases the difficulty of gold extraction.<\/p><p>Placer gold is usually associated with<strong> specific types of associated minerals<\/strong>: in alluvial deposits, it is often associated with heavy minerals such as magnetite and ilmenite; coastal placer gold is often co-enriched with zircon and monazite.

It requires comprehensive recovery through the beneficiation process of the main ore. Its mineralization mechanism is closely related to large-scale magmatic-hydrothermal activity: when intermediate-acidic magma rich in metallic elements intrudes into the shallow crust, it triggers long-term hydrothermal circulation. Gold migrates along with ore-forming elements such as copper and molybdenum through chloride complexes, accumulating as microscopic inclusions or lattice substitutions in minerals such as chalcopyrite, pyrite, and galena during sulfide crystallization.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-c9b80eb elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"c9b80eb\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-346b15c\" data-id=\"346b15c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-d61b278 elementor-widget elementor-widget-heading\" data-id=\"d61b278\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Caract\u00e9ristiques principales<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-244ae3a elementor-widget elementor-widget-text-editor\" data-id=\"244ae3a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>\u00a0The core economic value of associated gold ore lies in its low-grade, large-scale resource characteristics.
