The tin ore processing process is carried out by separating the concentrate and tailings contained. In its application, there are still many valuable minerals that escape and are wasted through tailings, causing the potential for low-grade tin ore from the rest of the processing process (SHPP). To optimize the processing of tin ore, it is necessary to carry out further processing, one of which …
The research was conducted on the PT Minevesting Resources Indonesia silica mining project, which is still in the feasibility study stage. To ensure the economic feasibility of developing the mine, a comprehensive study of the project's financial aspects and sensitivity was conducted. The indicators used included Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP). …
Aspal merupakan salah satu sumber daya alam yang tidak dapat diperbaharui, sehingga apabila digunakan secara terus menerus pada suatu saat nanti persediaannya akan habis. Selain itu harga aspal relatif mahal, walaupun aspal hanya merupakan komponen kecil dalam kontruksi perkerasan jalan. Sehingga perlu dilakukan penelitian untuk mencari bahan alternatif sebagai pengganti sebagian aspal dalam ca…

Background: Caries is the most common oral health problem that occurs on children. Calcium deficiency due to demineralization of the enamel could be anticipated with application of remineralization materials. One of the natural alternatives to support remineralization process is quail eggshells (Coturnix coturnix) containing high calcium carbonate as hydroxyapatite precursor. Objective: To know…
Energy and minerals are important in the survival of human beings in modern times, the energy used to make it easier for people in the activity every day. Indonesia is rich country in natural resources mainly energy and minerals. South Sumatra alone has 42% of the potential energy and minerals from all over Indonesia, but human resources competent for the processing of energy is still very litt…
Suseptibilitas magnetik merupakan kemampuan suatu bahan untuk termagnetisasi beerdasarkan nilai suseptibilitasnya.

Pengukuran nilai suseptibilitas magnetik dilakukan dengan menggunakan alat Bartington Susceptibility Meter…
PT. Timah (Persero) unit Metalurgi process and refme tin ore. Not only tin ore, but also process the valuable associated minerals, one of them is Ilmenit (FeTiOj). Associated minerals is processed in Amang Plant, “Bidang Pengolahan Mineral” (BPM). Ilmenit is a paramagnetic mineral, so that to separate it from the other minerals the high current is required to obtain the strong magnetic inte…
Earth has become a huge mine, with a greater quantity and variety of fundamental mineral resources being extracted year after year. Technology, from electric cars to everyday electrical equipment, consume vast amounts of scarce raw materials. On a planet with limited resources, are these minerals being properly assessed? Will there be enough raw materials to meet the demand of a world populatio…
