ما الذي يتنقّل فعلاً
Oxidised copper minerals dissolve in sulfuric acid. That means the metal can be leached, extracted and plated into finished cathode at the mine site, and leave the country as a 99.99% product rather than as a concentrate. It is the same metal as the Chilean route and a completely different journey.

خطوة خطوة، وحدًّا حدًّا
Democratic Republic of the Congo · Kolwezi, Lualaba بحوزة Operators with Gécamines as state partner (شركة التعدين)
A richer orebody than most
Open-pit and underground mining of sediment-hosted ore that runs several times the grade of a typical porphyry.
لماذا هنا: The Central African Copperbelt is one of the richest copper provinces on Earth, and it carries cobalt with it.
Democratic Republic of the Congo · Hydrometallurgical plant on site بحوزة Operators (كيميائي)
Leaching with acid
Crushed ore is leached in sulfuric acid. Copper and cobalt dissolve together into a pregnant leach solution.
ما الذي جرى للباقي: Acid is trucked in or made on site. In a landlocked country, the reagent supply chain is as hard as the metal one.
لماذا هنا: No smelter needed, so no reason to ship the ore anywhere.
Democratic Republic of the Congo · Same plant بحوزة Operators (المكرِّر)
Solvent extraction and electrowinning
An organic solvent picks the copper selectively out of the solution and releases it into a clean electrolyte; current then plates it onto cathode blanks. Cobalt is precipitated separately as a hydroxide.
لماذا هنا: This is the whole point of the route. The finished metal is made at the mine, in the country that owns the orebody.
South Africa · To Durban, Dar es Salaam or Beira بحوزة Hauliers and traders (متداول)
Two thousand kilometres by road
Cathode is bundled and trucked across one or two borders to a port. Delays at the border are measured in days.
لماذا هنا: Being landlocked is the permanent tax on this journey — and it is why the cobalt beside it travels the same road.
China · Wherever it is bought بحوزة Fabricators (الشركة المصنّعة)
Straight into the wire market
Cathode from Kolwezi is the same product as cathode from Guixi and trades on the same terms. Nobody downstream can tell which route it took.
لماذا هنا: Once it is cathode, copper is copper.
هذا مثال تطبيقي. يتتبّع كمية ابتدائية محددة عبر معدلات عائد واسترداد نموذجية منشورة، مما يجعل النسب قابلة للتحقق؛ وهو ليس سجلاً لشحنة فعلية. وقد جُمعت وقائع المسار — الدول، والعمليات، وأسباب تعذّر معالجة المادة في مكان آخر — من تقارير متاحة للعموم.
