Sektor pertambangan merupakan salah satu bisnis yang paling berisiko, padat modal, dan berteknologi maju. Oleh karena itu, setiap tindakan yang diambil di sektor ini harus dipikirkan dengan matang. Ketika material non-bijih (limbah) bercampur dengan material bijih selama operasi penambangan, efeknya adalah pengenceran, yang meningkatkan tonase sekaligus menurunkan kadar rata-rata. Penelitian ini bertujuan untuk mengetahui apakah terjadi dilusi dan apa saja faktor-faktor yang menyebabkan terjadinya dilusi kadar bijih nikel dan berapa persentase penurunan kadar. Metode penelitian yang saya gunakan adalah metode pengambilan sampel kemudian dilakukan proses preparasi dan dilanjutkan proses analisis. Hasil penelitian tersebut menunjukkan bahwa, setelah pembukaan lahan selama tahap persiapan penambangan, pencampuran tanah pucuk dan material lapisan tanah penutup yang tertinggal di lokasi front penambangan merupakan penyebab terjadinya pengenceran. Pengenceran dapat terjadi selama operasi pengumpulan bijih karena ekskavator yang digunakan untuk membuang limbah dan material overburden adalah ekskavator yang sama, yang dapat mempengaruhi pengenceran. Karena alat pemuatan excavator menggunakan material bijih sebagai titik tumpu untuk memuat bijih, maka proses pemuatan bijih dapat mengakibatkan pengenceran. Kesimpulan penelitian ini adalah pada kegitan penambangan pada Blok C PT Jagad Rayatama mengalami penurunan kadar dengan faktor terjadinya dilusi disebabkan oleh alat yang digunakan dan Persentase penurunan kadar antara sampel produksi dan sampel stockpile sebesar 0,22%.
