Sejarah Penambangan Timah Di Dunia

Pertambangan timah dimulai pada awal Zaman Perunggu, perunggu adalah paduan tembaga-timah. Tin adalah elemen yang relatif langka di kerak bumi, dengan sekitar 2 ppm (bagian per juta), dibandingkan dengan besi dengan 50.000 ppm.

Sejarah Timah

Penggunaan dan Ekstraksi timah menjadi awal dari dimulainya Zaman Perunggu sekitar 3000 SM, ketika diamati bahwa benda-benda tembaga terbentuk bijih polimetalik dengan kandungan logam yang berbeda memiliki sifat fisik yang berbeda. Perunggu pada masa itu memiliki kandungan timah atau kandungan arsenik kurang dari 2% dan karena itu diyakini sebagai hasil dari paduan yang tidak disengaja karena melacak kandungan logam dalam bijih tembaga. Dari situ segera ditemukan bahwa penambahan timah atau arsenik untuk tembaga meningkatkan kekerasannya dan membuat pengecoran lebih mudah, yang merevolusi teknik pencampuran logam dan membawa manusia dari Zaman Tembaga atau Chalcolithic ke Zaman Perunggu sekitar 3000 SM. Eksploitasi timah pada awalnya telah berpusat pada deposit placer dari kasiterit.

Bukti pertama penggunaan timah untuk membuat perunggu muncul di wilayah Timur dan Balkan sekitar 3000 SM . Sampai hari ini masih belum jelas di mana timah pertama kali ditambang. Penambangan timah pertama di Eropa tampaknya berawal dari Erzgebirge, di perbatasan antara Jerman dan Republik Ceko tahun ke 2500 SM . Dari sana timah diperdagangkan utara ke Laut Baltik dan selatan ke Mediterania mengikuti rute perdagangan Amber Road. Pengetahuan penambangan timah menyebar dari Erzgebirge ke penjuru daerah penambangan timah Eropa lainnya dan terbukti dari mulai munculnya penambangan timah di Brittany , Devon, Cornwall , dan di Semenanjung Iberia sekitar 2000 SM .

Deposit tersebut di eksploitasi secara besar-besaran jatuh di bawah kendali Romawi antara abad ketiga SM dan abad pertama Masehi. Permintaan timah menciptakan jaringan yang besar dan berkembang antara budaya Mediterania Klasik. Pada periode abad pertengahan , sebagian besar deposito Iberia dan Jerman mulai dilupakan sementara Devon dan Cornwall mulai mendominasi pasar timah Eropa.

Jauh di Timur , sabuk timah yang membentang dari propinsi Yunnan di Cina ke Semenanjung Malaysia mulai dieksploitasi kira-kira antara milenium ketiga dan kedua SM . Deposit di propinsi Yunnan tidak ditambang sampai sekitar 700 SM , namun oleh Dinasti Han telah menjadi sumber utama timah di Cina sesuai dengan teks sejarah dari Han , Jin , Tang , dan dinasti Song .

Daerah lain di dunia banyak mengembangkan industri pertambangan timah di kemudian hari. Di Afrika , budaya Bantu untuk mengekstrak , melebur dan mengekspor timah berlangsung antara abad ke-11 dan ke-15 Masehi. Di Amerika eksploitasi timah dimulai sekitar 1000 Masehi , dan di Australia dimulai dengan kedatangan bangsa Eropa pada abad ke-17 .
