ABSTRAK
Pada tahun 2023 PT Meares Soputan Mining ingin meningkatkan target
throughput secara keseluruhan, dengan tetap mempertahankan terget ukuran produk
overflow hydrocyclone yang berkisar antara 100-106 μm. Salah satu solusi yang
bisa dilakukan untuk meningkatkan target throughput yaitu dengan melakukan
perubahan desain pada cluster hydrococylone sirkuit SAG Mill. Penyesuain desain
berupa perubahan type hydrocyclone baru yaitu 400CVD pada sirkuit SAG Mill
yang saat ini digunakan. Trial hydrocyclone type 400CVD rencananya akan
dilakukan trial dengan total 1 unit pada cluster hydrocyclone sirkuit SAG Mill.
Peneltian ini bertujuan untuk menganalisis pengaruh persen solid umpan
terhadap perolehan aliran produk underflow dan overflow, P80 produk overflow dan
efisiensi hydrocyclone type 400CVD dan 400CVX. Perbandingan kedua
hydrocyclone dilakukan dalam variasi spigot 100mm dan 110mm untuk type
hydrocyclone 400CVD dan 110mm untuk hydrocyclone type 400CVX. Selama
penelitian berlangsung tidak dilakukan perubahan pada parameter operasi yaitu
persen solid umpan yang berkisar antara 50-65%.
Didapatkan hasil penelitian yang telah dilakukan bahwa peningkatan persen
solid umpan berpengaruh terhadap persen solid underflow, overflow dan P80 produk
overflow pada hydrocyclone. Semakin besar persen solid umpan maka akan
menghasilkan persen solid yang besar pada produk overflow dan menurunkan
persen solid produk underflow. Hal ini tidak berlaku pada hydrocyclone 400CVD
spigot 110m dikarenakan terdapat anomali data yang diakibatkan oleh beberapa
faktor, diantaranya perolehan air pada kedua aliran produk, kenaikan ukuran
diameter spigot dan kemungkinan terjadinya keausan pada liner hydrocyclone
sehingga mengakibatkan proses klasifikasi yang terjadi tidak berlangsung secara
optimal. Pada ukuran produk overflow 106 μm didapatkan bahwa efisiensi
hydrocyclone type 400CVD untuk spigot 100mm lebih baik dimana sebanyak 12%
dari partikel tersebut akan ke aliran produk underflow dan 88% sisanya akan
menuju aliran produk overflow, dibandingkan dengan hydrocyclone type 400CVX
untuk spigot 110mm yaitu sebanyak 45% dari partikel tersebut akan masuk ke
aliran produk underflow dan 55% sisanya akan menuju aliran produk overflow.
Sementara itu efisiensi pada hydrocyclone type 400CVD spigot 110mm lebih buruk
dimana sebanyak 24% dari partikel tersebut akan masuk ke aliran produk underflow
dan 76% sisanya akan menuju aliran produk overflow, dibandingkan dengan
hydrocyclone type 400CVX spigot 110mm sebanyak 18% dari partikel tersebut
akan ke aliran produk underflow dan 82% sisanya akan menuju aliran produk
overflow.

ABSTRACT
In 2023 PT Meares Soputan Mining wants to increase the overall throughput
target, while maintaining the grand size target of the hydrocyclone overflow
product which ranges 100-106 micron. The solution to increase the throughput
target is to make design changes to the hydrococylone cluster of the SAG Mill
circuit. Design change in the form of a new hydrocyclone type change to 400CVD
in the SAG Mill circuit currently in use. Trial hydrocyclone type 400CVD is
planned to be trialled with a total of 1 unit in the SAG Mill circuit hydrocyclone
cluster.
This research is to review the effect of feed solid percentage on the flow
recovery of underflow and overflow products, P80 of overflow products and
efficiency of hydrocyclone type 400CVD and 400CVX. The comparison of the two
hydrocyclones was carried out at 100mm and 110mm spigots for hydrocyclone type
400CVD and 110mm for hydrocyclone type 400CVX. During the research no
changes were made to the operating parameters (feed solid which ranged from 50-
65%).
In the results of the research that has been done, it can be seen that increasing
the percent solid feed effects the percent solid underflow, overflow and P80 of
overflow products on the hydrocyclone. The greater the feed solid percent, the
greater the solid percent in the overflow product and the lower the solid percent of
the underflow product. This does not apply to the 400CVD spigot 110m
hydrocyclone because there are data anomalies caused by several factors, including
the acquisition of water of splitt to product underflow and overflow, the increase in
spigot diameter size and the possibility of wear on the hydrocyclone liner resulting
in the classification process that occurs not taking place optimally. At an overflow
product size of 106 microns, it was found that the efficiency of hydrocyclone type
400CVD for 100mm spigot is better where as many as 12% of the particles will go
into the underflow product stream and the remaining 88% will go to the overflow
product stream, compared to hydrocyclone type 400CVX for 110mm spigot which
is as many as 45% of the particles will go into the underflow product stream and
the remaining 55% will go to the overflow product stream. Meanwhile, the
efficiency on the hydrocyclone type 400CVD 110mm spigot is worse where as
many as 24% of the particles will enter the underflow product stream and the
remaining 76% will go to the overflow product stream, compared to the
hydrocyclone type 400CVX 110mm spigot as many as 18% of the particles will go
to the underflow product stream and the remaining 82% will go to the overflow
product stream.
